----------------------------------------------------------------------------- MEKA - ChangeLog ----------------------------------------------------------------------------- Note: for a more developer/hacker centric ChangeLog, download source code and refer to HISTORY.TXT file. ----------------------------------------------------------------------------- MEKA 0.73 --------- - Updated MEKA license, data are now licensed under the same term as sources. The license is now unrestrictive BSD-like. [Omar] - Removed "k" and associated donation rambling from the documentation. Donations are still welcome, at your own discretion. - Emulation: - Added support for "no bank switching" mapper. Used by Korean games such as "FA Tetris" and "Flash Point" which write to $fffe-$ffff range for its RAM usage but do not expect bank-switching. [Omar] - Added support for Korean 8KB banks mapper. Used by Korean games ported from MSX such as "Penguin Adventure", "Street Master" or "Won-Si-In". [Omar] - SC-3000: - Fixed the ;/+/RAD key not working on Sega Keyboard emulation under certain host keyboard/OS configuration. Thanks Jacko. [Omar] - Fixed crash in the X86 assembly implementation of the 32KB RAM mapper writer when the upper 16 bits were not cleared by the Z80 emulator. [Omar] - Debugger: - Added "SYM @addr" command to search for symbols given an address. [Omar] - Added "RMAP addr" command to reverse map of a Z80 address and display the source of data based on machine state (mapper registers, etc). eg: RMAP $8001 ; eg: print 'ROM $14001 (Page 5 +0001)' RMAP $E001 ; eg: print 'RAM $C001' The feature doesn't work 100% in all mappers & bus mirroring cases, but should be ok with the standard SMS/GG mapper. [Omar] - Duplicate commands are automatically removed from history. [Omar] - Increased default height of the debugger. [Omar] - Changed watch point per-frame flood limit from 100 to 50. Will expose in configuration file if requested. [Omar] - Fixed crash when loading symbols with debugger disabled. [Djbass,Omar] - Fixed labels showing one instruction early in "DASM" command. [Omar] - Added breakpoint '!' mark in disassembly window. [Omar] - GUI: - Fixed Light Phaser and Terebi Oekaki cursor shape when switching from 32-bits GUI mode to 16-bits game only mode. [Omar] - File browser: fixed positionning of BAD and HACK icons, which aren't overlays anymore. [Omar] - Added Canadian flag (for DB and File Browser). [Omar] - Fixed crash when empty gradient range are specified in theme file. [Omar] - File browser: country flag now displayed even on BIOS, Prototypes or Homebrew images. [Omar] - Inputs configuration: right-click on input source selection goes backward, in addition to regular left-click to go forward. [Omar] - Localization: - Updated Dutch localization [Mark van Tilburg] - Miscellaenous: - Added "Capture" menu with screen capture menu access and options. [Maxim] - Added "Capture All" mode, capturing all emulation frames to disk. [Maxim] - Added "Include GUI" capture option. Disable to only capture game screen when MEKA GUI is enabled. [Maxim] - Renamed "Automatically crop and align screen captures" option to more explicit "Crop and align screen captures to 8x8 boundaries". Previous name was sounding too "cool" and was sometimes activated by innocent users who then got their capture all cropped. [Omar] - Added "screenshots_crop_scrolling_column" option in configuration file (default to enabled), to disable cropping the empty left-most column in horizontally scrolling games. [Omar] - Project: - (Win32) Fixed standard libraries used by debug builds (using unusual combination led to various problems). Fixed various link warnings. Fixed shared directories between DLL and No DLL builds. [Omar] - Added and modified entries in the checksum and compatibility lists.

[Proppy] Compile and run under a x86-based MacOSX system. Missing sound (due to Seal) and debugger (unknown problem to resolve). Looking for someone who wish to improve and maintain this port. - Video/Blitters: - Upgraded everything to hi-color video modes and got rid of old, 8-bit indexed video modes. This is a major change in MEKA core. Some of the benefits are: - No more snow and/or color flickering on video card drivers which disliked palette changes. - Better integration with desktop (usually run faster). - Getting possible to use various kind of graphics filters. - No more hassle with color limitation for the programmer (meaning more features implemented for the end-user). - Finally possible to show all Game Gear colors at once, and to implement LCD screen persistence (not yet done). Some of the features above goes hand to hand with the blitter system, which will be improved soon. [Omar] - Fixed HQ2X stretched blitter when target output was not 16-bits. [Omar] - Stretching works on all blitters. [Omar] - Video depth, Vsync, Triple Buffering and Page flipping are now global video settings, removed from each specific blitter. Greatly simplify configuration and tweaking. [Omar] - Triple buffering doesn't interfere with the refresh is not supported by the current settings (eg: windowed mode), making it safe and more simple to always leave it enabled. [Omar] - Changed default fullscreen blitter configuration in the hope of getting something more compatible (640x480 by default), as so many people have problems with fullscreen modes. - Removed obsolete "scanlines" blitter, in favor of "tvmode". [Omar] - Removed "parallel" blitter that displayed both odd and even frame next to each other. Seems useless now. Could be brought back if some four-eyed person request it. [Omar] - Sound: - Added support for VGM 1.10 header type. [Omar] - Emulation: - Fixed data corruption/overflow in VDP emulation when seeking and writing to an invalid palette address. Thanks Maxim. [Omar] - VDP palette write do not mask out current VDP address, so performing the (unprobable) set address/access palette/access VRAM sequence will keep address in the full 16KB range. [Omar] - Fixed VDP line interrupts not properly running in overscan area in 224 lines mode. Fixes bottom of the screen in Charles Mac Donald's BB2K6 demo. [Omar] - CPU: - Z80: Fixed cases were address arithmetic would not wrap in the 16-bit address space, effectively crashing the emulator (those cases were mostly happening on corrupted data, but it also legit Z80 code, and in any case we don't want the emulator to crash). [Omar] - Z80: Fixed RETI behavior (same as RETN, copying IFF2 to IFF1). Fixes pausing in SMS Robocop 3 during legal screens/introduction, probably other infrequent cases. [FluBBa, Omar] - Z80: Accepting NMI doesn't copy IFF1 over IFF2, as suggested by Sean Young's "The Undocumented Z80 Documented". [Omar] - ColecoVision: - Fixed emulation of pending NMI, pending flag is cleared when reading VDP status. Fixes "Rock 'N Bolt" among other. Thanks to the anonymous poster on SMS Power! forums. [Omar] - Note that the compatibility list for ColecoVision titles is severly outdated. At some point, James Carter worked on a new, more accurate list, but I lost all contact with him. - Removed detection of supposed 128-bytes headers and 512-bytes footers (from some old soft/copiers?), due to many false detections, particularly on homebrew ROM images (the code was introduced in 2001 when Dig Dug and Pac-Man prototypes were released with such header, but ROM images now circulating are without the header). [Omar] - GUI: - Sorted default themes, removed non Sega 8-bit related themes. Now embedding background pictures in regular binary distribution. CALL FOR NEW OR IMPROVED THEMES SUBMISSION! Please contribute. - KeyPad Enter key now works on input boxes. [Omar] - Added shortcut CTRL-F4: closes current window. [Omar] - Added shortcut CTRL-TAB: cycles thru windows taking inputs. [Omar] - Reworked theme (skin) system from stratch: [Omar] - Changed MEKA.THM file format. - Using explicit names for variables. - Added more variables, making the skin system a little more complicated but also more configurable. - Using de-facto standard of specifying colors in #RRGGBB format. - Rewrote most code since it was all legacy from old MEKA 0.10. - Added link to debugger documentation in HELP menu. [Omar] - Removed closing fadeout since the current hi-color implementation is way inefficient and cannot garantee proper speed. [Omar] - Development: - Debugger: - Fixed various command-line parsing bugs. [Omar] - Added line history. Navigate history by pressing Up/Down. List or search in history using HISTORY (HI) command. [Omar] - Added conditionnal breakpoints. [Omar] eg: BREAK r C000.. =01,02,03,04 ; break on read of 01020304 in RAM BREAK x =C9 ; break on CPU execution of RET BREAK x =0,0 ; break on CPU execution of NOP NOP BREAK w pram 0 =03 ; break on PRAM write of color 0 as red - Added display line event breakpoints/watchpoints. [Omar] Useful for debugging line interrupts. eg: BREAK line #13 ; break on display line 13 - Added "B nopnop" shortcut to break on two successives NOP instructions. This is basically equivalent to "B x =0,0". [Omar] - REGS (R) command in debugger now display shadow registers as well. [Omar] - Added cursor before current instruction in disassembly. [Omar] - Added access to shadow registers in expression evaluator. [Omar] eg: PRINT AF',BC',DE',HL' - Added SET command to modify Z80 registers. [Omar] eg: SET BC=$1234 ; set BC register to $1234 SET DE=HL,HL=0 ; set DE=HL, then zero HL - Added MEMEDIT command to spawn a new memory editor. [Omar] - Added CLOCK command, to display/reset a Z80 cycle counter. Very simple but can be helpful to time Z80 routines. [Omar] - (Win32) Forward debugging log to Windows debugging stream via OutputDebugString(), so running MEKA from Microsoft Visual studio will display log in the 'Output' window. [Omar] - Memory Editor: - Added viewing and editing of VDP registers (VREG). [Omar] - Added configuration file directive for resizing window. [Omar] - Fixed cursor position when inputing an address on last page. [Omar] - Added NES PRAM support. [Omar] - Tiles viewer: - Added NES palette switching (8 palettes). [Omar] - Tilemap viewer: - Added tilemap viewer. [Omar] Shows tilemap, hovering or clicking a tile shows specific info about it, allows filtering BG/FG, disabling tile flipping, display of scrolling box, with or without raster effects, manual selection of tilemap address, etc. - Made '$' default prefix for hexadecimal values in various places. [Omar] - Datadump: [Ambil, Omar] - Fixed "palette" dumping. Blue and green components were inverted. Replaced dumping of target host RGB values by actual SMS/GG components. - Added sprite pattern base address in "sprites" dumping. - Cleaned Technical Information Viewer content, renamed a few fields to their official names, removed redundant information. It's not yet all clean. [Omar] - Miscellaenous: - Various fixes. - Increased max length of directory/filenames. [Musuruan] - Added "Automatically crop and align screen captures" option. This option aligns screen captures on the nearest visible tile, helping to simplify the process of creating game maps by pasting captures next to each other. [Omar] Note: May not work properly on game using scanline based effects. - Updated various tidbits in the configuration file. [Omar] - (Win32) Removed flickering from initialization message console. [Maxim] - (UN*X) Renamed main executable to 'meka' (instead of 'meka.exe'). - Sources/Project - (Win32) Added new targets supporting shared standard libraries. [Omar] - (Win32) Updated Allegro library from WIP 4.1.18 to 4.2.0, including various fixes/improvements: http://www.talula.demon.co.uk/allegro/onlinedocs/en/changes.html - (Win32) Now linking to zlib.lib instead of zlibs.lib (name for standard static build of ZLIB). [Omar] - Removed password encryption from MEKA datafile (became useless). [Omar] - Fixed a bunch of warnings on higher warning levels. [Omar] - Hacked a lot of old GUI code (box, widgets, menus among others), cleaned and renamed various structures, replaced several usage of indexes by pointers, added const qualifiers, rewrote parts of various applets, got rid of some old obsolete code, etc. Hopefully broke nothing. [Omar] - (Win32) Fixed MSVC project to reference LIBPNGDIR. - (Win32) Including statically compiled libpng.lib in package. [Omar] - (UN*X) No more need to manually edit .ASM files to compile. [Omar] - Updated SOURCES.TXT documentation. [Omar] - Added and modified entries in the checksum and compatibility lists.

[DjRobX] Made triple buffering the default for appliable video modes. It might or not work on all configuration. Please report if any problem arise. - Added max stretch support on fullscreen blitters. [DjRobX] This is currently only available on normal and HQ2X filter. Integer/ratio stretch not yet supported, so it is recommended to use a resolution multiple of the emulated system screen size. - Added support for internally converting the 8-bit video buffer to another video depth and blitting that. [DjRobX] - Integrated Maxim Stephin's HQ2X graphics filter, and added a dedicated blitter. Only 16-bits output is supported as of yet. [MaxSt,DjRobX] - GUI: - Fixed input box widget missing keys on skipped frames. [Omar] This made key inputs very annoying on certain configuration, and especially with 3-D glasses auto-frame-skipping enabled. - Fixed a problem losing focus while dragging GUI windows with certain kind of widgets (happened on tile viewer & memory editor, among other). [Omar] - Development: - Updated debugger documentation. [Omar] - Added symbol loading in NO$GMB format, as generated by the commonly used WLA DX linker (-s parameter). [Omar] - Added label/symbol viewing in Z80 disassembly window. [Omar] - Relative offsets are now resolved in Z80 disassembly window. [Omar] - Added expression evaluator. [Omar] Supports integer operators +,-,*,/, binary operators &,|,^, parenthesis, symbols and CPU registers replacement. Yet missing: unary operators -,!,~. All commands uses the expression evaluator to get their numeric parameters, so you can use it everywhere. eg: B function ; break at given 'function' symbol M my_data ; memory dump from 'my_data' symbol - Added PRINT (P) command to evaluate and print expressions. [Omar] eg: P IX,IY ; print IX and IY registers P 1200+34 ; print $1234 P %00101010 ; print 42 P HL+(BC*4) ; print HL+BC*4 P label ; print label - Added contextual command line completion. [Omar] Press TAB to complete current input with matching command/symbols. eg: b[tab] ; -> BREAK b[tab]la[tab] ; -> BREAK label - Added SYMBOLS (SYM) command to list and search for a symbol. [Omar] - Changed breakpoint/watchpoint range syntax to '..' to avoid any syntaxical ambiguity with substraction (eg: B 1000..2000). [Omar] - Added "B ENABLE/DISABLE ALL" shortcuts to enable/disable all breakpoints at once. [Omar] - Added "B CLEAR DISABLED" shortcut to clear disabled breakpoints. [Omar] - Added "Reload ROM" functionnality in the debug menu, for quicker reload. - Palette viewer now shows color entry data while hovering colors. [Omar] - Fixed display of CPU flags (only bit 0 was properly interpreted, because of a typo). Added display of undocumented flags bits 3 and 5 (partially emulated). [Omar] - Made it that debugger log to file is immediately flushed. This allows reading the log file in live while the debugger is running. [Omar] - Added REGS (R) command to dump Z80 registers to the log console. [Omar] - Added animation displaying weither CPU is running or not. [Omar] - Fixed behavior of step/step over/continue when executing while being located on a breakpoint. [Omar] - Fixed behavior of step over an infinite loop. [Omar] - Miscellaenous: - (Win32) Added a "setup.bat" command file to run the interactive setup. Seems like few people were aware of the command-line option. [Omar] - (Win32) The interactive setup now offers to enable/disable the debugger, so you don't have to manually enable it. [Omar] - (Win32) Updated Allegro library from WIP 4.1.12 to 4.1.18, which includes various fixes/improvements: http://www.talula.demon.co.uk/allegro/onlinedocs/en/changes.html - (Win32) Fixed crash on early aborting (eg: command line error) due to non properly stopping joystick polling thread. [Omar] - Fixed loading of corrupted or incorrectly sized ROM images that would sometimes made the engine crash. [Omar] - Updated various tidbits of documentation. [Omar] - Added and modified entries in the checksum and compatibility lists. [Omar] Some particular renaming includes: SMS - 60c19645 - Akai Koudan Zillion (JP) --> Zillion / Akai Koudan Zillion (note: this ROM was released in both Japan and Europe) SMS - a1710f13 - Lucky Dime Caper, The --> Lucky Dime Caper, The - Starring Donald Duck SMS - 5718762c - Zillion --> Zillion (US) GG - 7b7717b8 - Big War / Daisenryaku G (JP) --> Taisen-gata Daisenryaku G (JP) GG - a49e9033 - NBA JAM --> NBA JAM (JP) Note that DjRobX's video/blitter changes were integrated but some features may not be compatible with all others, and some need improvements. You are welcome to experiment different configuration settings in MEKA.BLT but not everything may work properly. The preset "HQ2X" blitter should works, though. The current blitter system makes it not trivial to do everything we want, it is too limited in configuration, and was first made with MS-DOS and low end computers in mind. As of next versions, I will work on reoverhauling the system, trying to better fits needs of the 21st century (resizing, multiple depth, hi-color, windowed modes without borders, non 4:3 ratio screens, different refresh rates...) and improve ease of setupping. Expect many changes in this area (hopefully). [Omar] - Sources/Project - (Linux) Updated Makefile and some sources tidbits for proper compilation. [Omar,Belegdol,Proppy] - (Linux,DOS) Object directories are now created automatically. [Omar] - (Linux,DOS) Removed "smscheck" tool building from Makefile. Has nothing to do with MEKA. [Omar] - (Linux,DOS) Added 'BUILD' switch in Makefile to select between release and debug builds. - (Win32) Make it that build date/time stamp in build.c is updated when rebuilding the solution. Removed buildupd.exe executable from sources. [Omar] - (DOS) I'm stopping to maintain the MS-DOS port. A maintener is welcome. [Omar] MEKA 0.70 --------- - Released source code. Added SOURCES.TXT file with some information for programmers. - Registration key is a thing of the past. It never served a real purpose other than identifying donators. All donators are publicly listed at: http://www.smspower.org/contrib.htm Big thanks to all of them for their great and useful support! I'll keep sending news/e-mails to donators. MEKA is now officially not having a registration procedure anymore, but your donations are still greatly welcome and are helping me to cover a part of my never-ending Sega 8-bit expenses, including buying cartridges for dumping and preservation purpose. I updated documentation to reflect this, and changed occurences of the "registration" word by "donation", as it was always meant to be anyway. - In SMS mode, fixed color filling when VDP rendering is disabled. Previously disabled parts where filled with black, instead of the current border color. No commercial game exhibited the problem. Chris Covell's port of Aleste 2 from GG to SMS did. - Disabling background display now shows a yellow-ish color instead of the black/border color, to help sprite ripping. Sorry it's not FF00FF pink, but I am currently lacking free palette entries, and anyway, a screen full of FF00FF pink would damage your eyes in a matter of seconds. :) - Development: - Added new full-featured breakpoints and watchpoints! - Manage multiple breakpoints/watchpoints. Add/remove/enable/disable. - Break and watch on CPU (rwx), IO (rw), VRAM (rw) and PRAM (w) buses. - Break and watch on specific access (read/write/execute). - Break and watch on single address or whole range. - Previous "B" command changed to "S" (step over). - Previous "B xxxx" command (one-time breakpoint) is still accessible using the "C" (continue) command. - Added detailed help for each command. (eg: "HELP B" to get help on breakpoints). - Instruction flow disassembly now attempt to display instructions before the current one, based on some magical voodoo technique of mine. Don't expect it to work in all cases - it is theorically impossible to do with variable-sized instructions anyway - but it can be improved. This feature helps figuring out what's being executed contextually. - The current instruction is now highlighted. - ROM edition in the memory viewer was not taken into account without a hard reset in region 0x0400-0x3FFF. Fixed. - Fixed savestate saving/loading which didn't restore scanline number properly, affecting debugging using those features. - Tile viewer now display tile starting address. - Tile viewer now update information while mouse hovering. - Added optional length parameter to "MEM" and "DASM" commands. - Fixed ASCII display of memory in "MEM" command. - Added "debugger_console_lines" and "debugger_disassembly_lines" variables in configuration file, allowing to change debugger size. Combine with a high-resolution MEKA desktop, and you can't be unhappy. - Added debugger session logging to file "debug/debuglog.txt". Can be disabled by clearing "debugger_log" in configuration file. - Fixed a bug using the memory editor to write to RAM in Coleco Vision mode. - Hacked a way so that you can affect controller inputs data while debugging (press a direction, it immediately apply on the emulated system state). - When used in the interface, analog peripherals supported by the mouse now only perform their action if the mouse has focus on the game window. This prevent accidental in-game shooting when using tools or debugging. Of course, you should not use the interface if you only intend to play. - Fixed /LOG command line parameter (broken recently). - Added and modified entries in the checksum and compatibility lists. Redumped more games, sorted more versionning/country confusion. To avoid certain confusion, all Game Gear games originally running in Master System mode were moved back in the Game Gear section. This makes the list consistant with actual cartridge releases. Some particular renaming includes: SMS - 17a40e29 - Alex Kidd in Miracle World (US) --> Alex Kidd in Miracle World [v0] (US) SMS - aed9aac4 - Alex Kidd in Miracle World --> Alex Kidd in Miracle World [v1] (note: this was released in both US and Europe) SMS - 08c9ec91 - Alex Kidd in Miracle World (JP) --> Alex Kidd no Miracle World (JP) SMS - 0df8597f - Basket Ball Nightmare --> Basketball Nightmare SMS - e421e466 - Borgman (JP) --> Chouon Senshi Borgman (JP) SMS - 11645549 - Solomon no Kagi (JP) --> Solomon no Kagi - Oujo Rihita no Namida (JP) SG - 0b4bca74 - Border Line (JP) --> Borderline SG - 922c5468 - Souko Ban (JP) --> Soukoban (JP) SG - 1ae94122 - Star Jacker [old] (JP) --> Star Jacker [v0] (JP) SG - 7f25deca - Star Jacker [new] (JP) --> Star Jacker [v1] GG - fe12a92f - Densetsu no Houguku (JP) --> Mickey Mouse Densetsu no Oukoku (JP) (terrible typo) GG - 937fd52b - Kaito Saint Tail (JP) --> Kaitou Saint Tail (JP) GG - dfa805a0 - Hanou no Toukyuuji Dodge Danpei (JP) --> Honoo no Toukyuuji Dodge Danpei (JP) MEKA 0.69b ---------- - [DOS/UN*X] Fixed ZIP file support which was accidently disabled in version 0.69. - Improved auto frame-skipper precision by a minor amount. (on another hand, it still manage to skip frames badly). - Disabled keys 0 to 9 to set a save state slot directly. Those conflicted with some existing and future features. Hope that noone will be annoyed! - Added ALT-ENTER hotkey to switch between fullscreen and windowed drivers. It works in both GUI and Game mode, although the setting is not saved in Game mode (due to the way the MEKA.BLT file works now). - Added an option to allows pressing opposite directions on the joypad. Although standard SG/SMS/GG controllers do not allow that, certain type of controllers (or a modified or broken one) may allow it. This serve the purpose of demonstrating a bug in "Wonder Boy in Monster Land", where pressing Left and Right on the same time confuses the game. It is also useful in the case some creative genius SMS programmer would want to take advantage of that weird feature to do unusual things for a soon-to-be released SMS software. - Fixed priority of Sega Keyboard (SK-1100) emulation, so that not colliding hotkeys are still available while SK-1100 is enabled. - Memory Editor now share inputs focus with game. It makes hacking easier. Of course you can always pause (F12) or remap controls if needed. - Fixed state of debugger window (bug introduced in 0.69). - Updated translations: - Dutch translation (by Mark van Tilburg). - Swedish translation (by Henrik Sankala). - Redneck translation (by some redneck in UK). - Added and modified entries in the checksum and compatibility lists. Some particular renaming includes: SMS - 31ffd7c3 - Castelo RETim Bum (BR) --> Castelo RETim-Bum (BR) SMS - b137007a - Desert Speedtrap --> Desert Speedtrap - Starring Road Runner and Wile E.

MEKA 0.69 --------- - Updated k. - Updated documentation. - Added a Memory Editor, long awaited by programmers, hackers and cheaters! It allows reading and writing to Z80 memory map, ROM, RAM, VRAM, Palette and Battery Backed RAM. Although it is not yet full-featured, it is already very possible to create your own Pro Action Replay codes, and perform various real-time hacks. Please share your questions and hacks on SMS Power forums: http://www.smspower.org/forum This tool is the result of joint work with my beloved girlfriend, who submitted a first version of it that she developped. - Added support for loading and saving pictures in PNG format. PNG is now the default format for screenshots, instead of the badly outdated PCX. (thanks to libpng). - Screenshots are now saved in the "Screenshots/" subdirectory. - Tweaked some themes, reordered them, removed a few. Themes backgrounds are now in PNG format. Please be sure to download the new picture pack at: http://www.smspower.org/meka/themes - [Windows] Added a message console that shows up on startup and magically disappear before you have time to read anything. If any problem occurs, the console will actually stay to let you read it. - [Windows] Fixed runtime application icon that wasn't showing. - [Windows] Removed command line parameters uppercase conversion (eg: when ran from Windows explorer). This inconveniently created uppercase output filenames for savestates, screen captures, etc. This was MS-DOS legacy. - Slighty optimized VRAM accesses emulation. - Incremented message buffer size to cope with SMS Chip-8 Interpreter 1.1 11k embedded comment. There is still buffer overflows in the code and I'm not trying to fix most of them now, so this is just a work-around. - Various other fixes and code tweaking. - Added and modified entries in the checksum and compatibility lists. Some particular renaming includes: SMS - 655fb1f4 - Bank Panic --> Bank Panic SMS - b4dfb825 - Bank Panic --> Bank Panic [BAD] SMS - 102d5fea - James Pond 2 - Codename Robocod --> James Pond II - Codename: Robocod SMS - e8ea842c - Marksman Shooting / Trap Shooting --> Marksman Shooting & Trap Shooting SMS - 00bef1d7 - Phantasy Star --> Phantasy Star [v3] SMS - 07301f83 - Phantasy Star [Saturn] --> Phantasy Star [Saturn] GG - c01293b0 - Devilish --> Devilish (US) GG - 06247dd2 - Ninku 2 (JP) --> Ninku 2 ~Tenkuryu-e no Michi~ (JP) GG - 00c34d94 - Madou Monogatari I (JP) --> Madou Monogatari I - Mittsu no Madokyu (JP) GG - 0a634d79 - Madou Monogatari II (JP) --> Madou Monogatari II - Aruru 16-sai (JP) GG - 12eb2287 - Madou Monogatari III (JP) --> Madou Monogatari III - Kyukyoku Joo-sama (JP) GG - 7ec95282 - Madou Monogatari A --> Madou Monogatari A - Dokidoki-Bake Shon (JP) GG - c169c344 - X-Men - Gamesmaster's Legacy --> X-Men - GamesMaster's Legacy Use SMS Checker for your ROM renaming needs! http://www.smspower.org/maxim/smschecker MEKA 0.68b ---------- As an experiment, I have enabled vsync in all default blitters and enabled it by default in the GUI. Blitters are still a bit complicated to configure so few people seems to actually tweak them or even enable the "smooth" blitter. Does it works better for you? I'll be working on synchronisation and blitter improvement (stretching...) in the future. - Removed the 2-byte tolerance in overdump detection. Overdumps with two slighty different half will be added in the database and marked as bad. - Emulation: - Fixed a major bug in the driver system, which resulted in corrupted savestates in F-16 Fighter / F-16 Fighting Falcon (the savestate system recognized them as SG-1000 games and so saved only part of RAM). Previous ingame states for the game are unrecoverable :( - Removed immediate palette update when CRAM is written in a legacy video mode (the palette isn't updated on a SMS). It only affected F-16 Fighter / F-16 Fighting Falcon, but in a non game-visible way. - Tweaked heuristical SMS/GG mapper detection. - Fixed SMS/GG scanline counter emulation which was ignoring TV type (NTSC or PAL/SECAM) override directive from the database. (eg: one game would be forced to PAL/SECAM mode, but scanline counter emulation still mimic an NTSC system if it is the user selection). - Fixed mouse button mapping in the Input Configuration applet. - Fixed file browser showing Japanese names after loading SMS Woody Pop or GG Pop Breaker (why those games only? because they both have a default country information in the DB, as they only works on Japanese systems). - Added and modified entries in the checksum and compatibility lists. Some particular renaming includes: GG - Ganbare Golby! (JP) --> Ganbare Gorby! MEKA 0.68 --------- Please report any problems you encounter. Suggestions are always welcome. - Updated MEKA.NAM database with a new format. The new format is more robust, includes CRC32, additionnal flags, and allows specifiying multiple countries for a same ROM file. In addition, while the MEKA database is being repopulated with entries in the new format, a high amount of verifications are being done on a case by case basis (redump, verified name based on original game media, box and manual, analysis of different versions of a same game, etc...). I have already redumped more than a hundred games. This will unsure having a near-perfect database after the transition. Old formatted entries are kept during the transition period. - SMS-mode Game Gear games are now autodetected and forced to run into SMS mode even with a .GG extension. This is because those games are often spread with a .GG extension, although there is no way in software to distinguish between a native GG game and one running in SMS mode, since the selection is done via a connected pin in the cartridge itself. - Updated file browser: - Added dedicated icons to known bad dumps, BIOS images, unofficial hacks, homebrew programs (also incorrectly called "public domain"), prototypes and unofficial translation. A translation is defined as a hack whose primary purpose is to alter the language of a game. How do you like my icons? - Added European, German, Italian, New-Zealand, Portuguese, Spanish, Swedish and United-Kingdom flags. All flags are now displayed with a border, because some themes may choose a window color matching some flags. - The "Load Names" feature is now faster and does not verbose any data to the message box while loading all files. - Made file browser window bigger by default. - Removed the auto-generated MEKA.VFN file, which was crap anyway. Instead, added a new auto-generated MEKA.FDB file, which store association between user ROM file names and MEKA DataBase entries. - Emulation: - Emulated VDP 315-5124 behavior of using register 5 bit 0 and register 6 bits 0-1 as masks on sprite x/tile attributes address and tile index. No known game relies on this feature, but it is good for the sake of accuracy and for developpers to check against this particularity in their code (it is often a coding mistake). VDP 315-5124 must be selected for that. - Updated TECH.TXT with SMS controller pinouts, simple SMS/DB-9 controller adapter instructions from Gary Pierce, and GNU/Linux notes. - Various other fixes and code tweaking. - Added and modified entries in the checksum and compatibility lists. - Naming and database field usage convention has been changed, based on the new format. - "Title (The)" now becomes "Title, The". - Unless specified by the game title, "Name: Subtitle" now becomes formatted "Name - Subtitle". - A few other things related to versionning/country. - Replaced all instances of "Tectoy" by "Tec Toy". - Added some missing accents. - Added many missing subtitles. - Added many new product numbers. Some particular renaming includes: SMS - Alex Kidd BMX Trial (JP) --> BMX Trial - Alex Kidd (JP) SMS - Ninja Gaiden [B] --> Ninja Gaiden SMS - Ninja Gaiden [A] --> Ninja Gaiden [Proto] SMS - Putt & Putter [B] --> Putt & Putter SMS - Putt & Putter [A] --> Putt & Putter [Proto] SMS - Smash TV --> Super Smash T.V.

(JP) GG - Putt & Putter --> Putt & Putter (JP) GG - Shinkinjoh (JP) --> Shikinjou (JP) GG - Tempo JR --> Tempo Jr. GG - Winter Olympics --> Winter Olympics (JP) The list above doesn't include ALL renaming, but only those I felt are the most important to be propagated. Many other renaming were done. MEKA 0.67 --------- - Updated documentation. - Tweaked the auto-frame skipper. Please let me know if you notice any improvement or new problem. - The analog Paddle Control is now usable using a digital keyboard or joystick input, although it is HIGHLY recommended to use a mouse. Playing with a keyboard or joystick may be sometimes frustrating and does not allows fast movements. - Updated debugging mode: - Scrapped old, buggy, and unusable MS-DOS only text mode debugger. - Added new debugger, well integrated into the GUI and functionnal with all versions of MEKA. It is a primitive debugger, but it can be helpful and it is definitively better than nothing. Supports step-into, step-over, breakpoint, jump, disassembly and memory dump. Expression are not evaluated and syntax is primitive. Enable with the /DEBUG command line parameter. - [Windows] Data dumping facilities are now working. - Updated patching system (see MEKA.PAT file): - Updated syntax. - Support for long awaited RAM patches! One of the side effect to that is that you can now apply PRO ACTION REPLAY codes easily. This feature is unfortunately not backuped by a full-featured interface and cheats database, but is helpful and better than nothing - while waiting for advanced cheating functionnalites to be added in the future. - Support for CRC32 to specify the game to apply patches on, as well as using MEKA proprietary checksum format. - Putting * in the CRC field will apply a patch to all games. - Minor bug fixes. - Inputs: - [Windows] Fixed joystick sliders support (DirectInput < 8.00 usually reports the fourth and fifth axis of a joystick as being sliders, which is a weird little known behavior). - File browser now takes exclusive inputs so the emulated game is not affected by keypresses. - Fixed file browser "Load Names" feature. It was broken in version 0.66, and sometimes (not always) went into an infinite loop in earlier version. - [Windows] Command line parameters help is now displayed in a message box. - Closing a box now automatically focus the next one in focus order. - Various other fixes. - Updated Dutch translation (by Mark van Tilburg). - Added and modified entries in the checksum and compatibility lists, on the road to perfection. Added many missing (J) flags in the Game Gear compatibility list. Added a few missing accents.

This is my top priority but I still cannot find a good solution to improve it and please everyone (slow and fast computers). I can't sleep! :( Use the "smooth" blitter if possible. - Updated default blitters (MEKA.BLT). - Video mode is not reinitialized anymore when switching blitters with the same resolution/refresh rate. This saves a bit of time. - [Windows] Fixed page flipping, for those using it (see MEKA.BLT file). - [Windows] Sega 3-D Glasses support is now properly working in MEKAW! If you build the simple 3-D Glasses to COM adapter (as described in the TECH.TXT file), it is possible to plug original 3-D glasses and enjoy 3-D games as they were meant to be played - and additionnally, damage your eyes due to intense flickering :) Best results are achieved by enabling page flipping or vsync. - [DOS] Sega 3-D Glasses support now also works under a Windows 95/98 command prompt. - Increased maximum number of joystick buttons to 32 (instead of 16). - Partly fixed incorrect joystick axis reporting. It was a problem for many people, and made it impossible or difficult to configure joysticks using the interface. One extended joystick axis may be missing now, until I can find a solution to this other problem. - Tile viewer can now be configured to displayed all 512 tiles, instead of the first 448 only. The bottom tiles looks awful with most SMS/GG games but some games use this area so it's good to see them. - Tile viewer now allows to select all 15 colors to display tiles in TMS9918 video modes (used by SG-1000, SC-3000, Coleco Vision, etc.). - Loading a ROM now display the full name in the message box. - [Windows] Upgraded MSVC compiler from version 5.0 to 7.1 (might bring a small improvement on performance). Removed ZLIB.DLL from the distribution and statically linked it to the executable. - [Windows] Fixed mekaw.cfg saving location. It was saving in a wrong place in some cases (depending how you run it). - Updated Danish translation (by Mark Klemp). - Added and modified entries in the checksum and compatibility lists. Some particular renaming includes: SMS - Asterix [A] --> Asterix [V0] SMS - Asterix [B] --> Asterix [V1] SMS - Chuck Rock 2 [A] --> Chuck Rock 2 [Europe] SMS - Chuck Rock 2 [B] [Brasil] --> Chuck Rock 2 [Brasil] SMS - Golfamania [1990] --> Golfamania SMS - Golfamania [1989] --> Golfamania (Proto) SMS - James Pond 2: Robocod --> James Pond 2: Codename Robocod SMS - Lemmings [A] --> Lemmings SMS - Lemmings [B] --> Lemmings (Proto) SMS - Mortal Kombat 2 --> Mortal Kombat II SMS - Pit Fighter [A] --> Pit Fighter [Europe] SMS - Pit Fighter [B] [Brasil] --> Pit Fighter [Brasil] SMS - Rainbow Island [A] --> Rainbow Island [Europe] SMS - Rainbow Island [B] [Brasil] --> Rainbow Island [Brasil] SMS - Seishyun Scandal [Japan] --> Seishun Scandal [Japan] SMS - Taz-Mania [A] --> Taz-Mania SMS - Taz-Mania [B] --> Taz-Mania (Proto) SMS - Tom and Jerry: the Movie [A] --> Tom and Jerry: The Movie SMS - Tom and Jerry: the Movie [B] --> Tom and Jerry: The Movie (Proto) SMS - Ultima IV [A] --> Ultima IV SMS - Ultima IV [B] --> Ultima IV (Proto) SMS - Wonder Boy 3: the Dragon's Trap --> Wonder Boy III: The Dragon's Trap (Proto) SMS - Woody Pop [Japan] --> Woody Pop: Shinjinrui no Block Kuzushi [Japan] GG - Lemmings [A] --> Lemmings GG - Lemmings [B] --> Lemmings (Proto) GG - Monster World 2 [Japan] --> Monster World II GG - Mortal Kombat 2 --> Mortal Kombat II GG - Wonder Boy 3: the Dragon's Trap --> Wonder Boy III: The Dragon's Trap (Proto) Please use SMS Checker for your ROM renaming needs! http://www.smspower.org/maxim/smschecker MEKA 0.65c ---------- - Fixed Z80 interruption timing. I have tested several "sensitive" games and nothing should have been broke, but please e-mail me if you notice anything unusual. In addition, the fix allowed to remove the need for a custom parameter in MEKA.NAM for 5 more games. - Fixed MEKA.PAT which added a bug to pausing in Wonder Boy III [SMS]. The bug was a leftover of one of my working session, and I forgot to remove it before releasing the official distribution of version 0.65b. - Fixed user inputs during the next frame after loading a savestate. Previously, they were reseted on savestate loading, meaning that your inputs were ignored on the first 1/60th second after loading. Although this is not dramatic in most cases, in a few it made savestates unusable because the player would die on loading without being able to react. Now you have that missing 1/60th second. - Attempted to fix the occasionnal crash on shutdown. I don't know if it happens anymore or not. - Updated Swedish translation (by Henrik Sankala). - Added and modified entries in the checksum and compatibility lists. Some particular renaming includes: SMS - Double Target [Japan] --> Double Target Cynthia no Nemuri [Japan] SMS - Formula 1 --> F1 SMS - Machine Gun Joe [Japan] --> Comical Machine Gun Joe [Japan] SMS - Pit Pot [Japan] --> Fushigi no Oshiro Pit Pot [Japan] SMS - Sonic the Hedgehog [A] --> Sonic the Hedgehog [V0] SMS - Sonic the Hedgehog [B] --> Sonic the Hedgehog [V1] SMS - Transbot --> TransBot GG - Columns --> Columns [Japan] GG - Formula 1 --> F1 GG - Pengo --> Pengo [Japan] GG - Jungle Book --> Jungle Book [USA] GG - Woody Pop --> Woody Pop [V0] Please use SMS Checker for your ROM renaming needs! http://www.smspower.org/maxim/smschecker/smschecker.htm MEKA 0.65b ---------- - Updated k. - Fixed TV Mode which was accidentaly broken in version 0.65 (due to recent palette system rewrite). Sorry for the inconvenience. I also took the occasion to slighty optimize it. - Fixed still screens corruption in Game Gear version of "Bart vs. the Space Mutants". It was affected by a timing issue introduced in a previous version. The fix (using a MEKA.NAM feature) is temporary until a better one can be found. - [Win] Added a simple first-run setup screen, to select soundcard, sample rate and language. Additionally, you can show the setup screen on startup by passing the -SETUP command line parameter to MEKA. - Added "cabinet_mode" setting in MEKA.INP, to invert ESCAPE and F10 keys. Arcade/emulation cabinet owners often have ESCAPE mapped to a key they want to use to quit. This feature is a quick addition until full key redefinition is supported. - Added auto-repetition on keys F6/F8 (savestate selection). - Added support for mouse wheel in file browser and documentation viewer. - Fixed state saving crash that could happen when sound is completely disabled and no FM emulator was selected. - Started migrating from my own general purpose C library to standard C library (LibC) for various functions. This should provides speed improvements in the initialization process. - Added and modified entries in the checksum and compatibility lists. - Various minor changes. Can you stop them all? MEKA 0.65 --------- - Rewrote palette system in the attempt of reducing palette changes even more. As some people noticed, on some computer, the Windows version had terrible slowdown and incorrect colors at some occasion and especially in Game Gear games. This is due to some DirectX video drivers which force waiting for a screen refresh before each palette change. Problem is that some drivers does that and some other do not. Palette changes in MEKA are now better grouped so that the wait should not affect gameplay in most cases. Please report if you notice any palette related problem in this version. Windows users, note that you can still get color flickering in some video modes. But overally, things should be much better. - Rewrote hardware sprite collision emulation for video modes 1, 2 and 3 (used by SG-1000/SC-3000/SF-7000/Coleco Vision software, mainly). Sprite collision are now processed line per line, for a very accurate result - at the cost of a slighty slower emulation. Although machines using those video modes usually can't poll for the current line, some software can manually do a similar job, making this precise value useful. This fixes "Froggy" and "Gold Miner" (SF-7000), and maybe more. Please report if you notice any collision related problem in this version. - Fixed SMS/GG scanline counter to return accurate values. - PAL/SECAM modes now have 313 lines instead of 312. - Fixed "Daffy Duck in Hollywood" (SMS) which in some cases had incorrect scrolling on the level score screen. - Fixed palette switching in "F-16 Fighter" / "F-16 Fighting Falcon", colors were incorrect during one single frame after the title screen. This bug was introduced in a previous release. - [Windows] Fixed screen capture (did crash with some DirectX drivers in version 0.64c). - Added Chinese flag in the file loader and associated the early dump of Hokuto no Ken with it. - Added and modified entries in the checksum and compatibility lists. Fixed a few inconsistent entries. Some particular renaming includes: Chase H.Q. --> Taito Chase H.Q. (official name) Story of Mio --> Hoshi Wo Sagashite... (official name) Hokuto no Ken [B] --> Hokuto no Ken Hokuto no Ken [A] --> Hokuto no Ken [China] - Updated documentation. - [UN*X] Released a quick & dirty GNU/Linux build, codenamed "MEKANIX". It is not perfect and I do not plan to completely support it, but I hope it can be useful to some people (some asked for it). Please read MEKANIX.TXT if you want to use it. MEKA 0.64c ---------- - Fixed the bug that would sometimes shut down sound when resetting or loading a savestate in full-screen mode. - Fixed the bug that would not save battery backed memory when switching the virtual machine Off (thanks Ian Hodgkinson for the precise report!). - Fixed Light Phaser border limit when left column is blanked. In some cases, the limit was enabled where it should not have. - Light Phaser is now usable inside of the GUI, although this is obviously not recommended since you can move the game window accidentally. - Redumped and verified plenty more cartridges. Added and modified entries to the checksum and compatibility lists, including new alternate dumps. Some particular renaming includes: James Bond 007: The Duel [B] --> James Bond 007: The Duel James Bond 007: The Duel [A] --> James Bond 007: The Duel [Brasil] Paperboy [B] --> Paperboy Paperboy [A] --> Paperboy [USA] Also modified compatibility list to be coherent with checksum list regarding alternate version naming. - MEKA now switch back to interface if fullscreen video mode cannot be set, instead of quitting. - Virtual machine picture positionning in the GUI now takes account of the resolution (in GUI another resolution than default 640x480 is used). - Updated history section of the documentation. - Added and modified entries in the checksum and compatibility lists. - [Windows] Fixed some of the screen corruptions when another application is getting the focus or writing to the screen (untested). - Added SG-1000 games to the multiplayer games list file (MULTI.TXT). - Updated Danish translation (by Marc Klemp). - Added CPU state dumping feature in debug mode. MEKA 0.64b ---------- - Added patches to be able to run SMS BIOS images (Alex Kidd in Miracle World, Hang On / Safari Hunt, Sonic the Hedgehog...) as standard games. - Fixed an amazingly stupid problem that's been around since years, which was that Game Gear colors were considered as 9-bits instead of 12-bits. Colors are now more precise, and you can notice a clear difference by looking at the ground in FIFA International Soccer. Thanks goes to Carleton Handley (the FIFA programmer on Game Gear) for clearly pointing that out to me. - Fixed VDP IE1 bit controls on Z80 IRQ Line. - Fixed top of the screen in video mode 3, and optimized its refresh. (used by Cabbage Patch Kids Picture Show and Smurf Paint & Play Workshop) - Added Danish translation (by Marc Klemp). - Patches write commands (in MEKA.PAT) now support multiple bytes in a single line. - Added and modified entries in the checksum and compatibility lists. - Added "Skydrop" theme by Peter Deas (need to uncomment it in MEKA.THM). - [Windows] Removed some unused bits in Allegro library and statically linked it within the executable, reducing the ZIP file by 150 Kb! MEKA 0.64 --------- Important changes were applied to the sound engine. As always, please contact me if notice something unusual, if you have any comment or doubt. PSG fixes that were applied in version 0.63 are apparently causing a bug to Out Run (SMS) running in FM mode. I searched but was unable to fix it as of yet. :( - Cleaned and modified various part of the sound engine. Please report if you notice anything unusual. - [Windows] Disabled access to hardware YM-2413 emulation using OPL under Windows 2000 and XP, avoiding crashes in certain cases... Well, this time it should works :-) - [Windows] FM Sound through OPL is now muted when switching to other applications. PSG can not muted yet due to a technical constraint. - Fixed muting of OPL on pause and quit (previously you were sometimes able to hear very low hanging notes with a very high volume). - Implemented software YM-2413 emulator by Mitsutaka Okazaki. Although hardware YM-2413 emulation using OPL sounds cooler, this emulator seems more faithful to the original chipset. It also works on all systems, including Windows 2000 and XP. The downside is that doing software synthesis takes a lot of time, and thus a fast computer is recommended (at least 600 Mhz) to play MEKA with software YM-2413 emulation. - Implemented a new software PSG emulator by Maxim (with modifications). PSG emulation is pretty straightforward, but this emulator takes account of several Maxim finds, such as the real sequence of pseudo random numbers, as generated by the noise channel. - Added refresh rate settings to GUI and Blitters. An advanced user can now setup a video mode at 60 Hz with vsync enabled and auto frame skipping disabled, for a smooth video refresh. - Fixed PSG output that was previously too low and unsigned. - [Windows] Attempted to fix some crashes subsequent to freeing a ROM. - Added entries to the checksum and compatibility lists. - Updated documentation. MEKA 0.63b ---------- - [Windows] Disabled access to hardware YM-2413 emulation using OPL under Windows 2000 and XP, avoiding crashes in certain cases. - Removed rare PSG debugging messages that were accidentally left. - Fixed timing of the {LD,CP,IN,OT}[ID]R transfer/comparaison Z80 opcodes, which were made too slow by 8 cycles in version 0.63. "The Castle" (SG-1000) was affected. - Fixed Sega Keyboard mapping for the "Yen" key on Japanese keyboard (untested). Note that the mapping for certain specials keys seems not to be right yet using the Windows version. - Performed some minor calling optimizations. - Updated Dutch, Deutsch, Italian, Spanish and Swedish translations with missing messages. (Thanks to their respective mainteners!) MEKA 0.63 --------- - Implemented a cyclic color allocation algorythm, reducing palette changes even more in some games. Users with videocard/drivers having problems changing palette can expect less slowdown in Game Gear games. - Tested every single Master System games, and wrote a multiplayer games list out of them. It is included in the emulator (MULTI.TXT). - Added 21 missing undocumented Z80 opcodes in the ED instruction set, including the wonderful OUT (A), 0. - Fixed PSG emulation. The holding note after text boxes shows in "Alex Kidd in Miracle World" is no more, and noise channel writes were fixed (as used by CodeMasters games: Micro Machines drums now sounds correctly, etc...). Thanks to the great Maxim for his informations! - Fixed Light Phaser shooting position for when left column blanking is enabled (a bug leaked in since a few version). - Fixed 64-bytes ROM footer detection. - Fixed a bug affecting Hardware Reset and ROM reloading on SG-1000/SC-3000 and Colecovision emulation. As far as I know, only "Pac-Man" (Coleco) was affected after an Hardware Reset, but other ROMs could as well. Thanks to James Carter for the bug report. - Fixed a two-years-old bug that may lead MEKA to crash when loading a savestate that was previously used under the debugger. - Fixed Sega Keyboard mapping for the unusual "Pi" / "Ro" key, so Japanese users can use it at its standard mapping location. Thanks to Yujiro for the bug report. - FPS Counter is now enabled/disabled by pressing Alt+F, instead of keeping F pressed. - [Windows] Fixed time display. - Updated to newer GCC version, hopefully little improving performances. - Added and modified entries to the checksum and compatibility lists. Some interesting ones I could rename after redumping: Alex Kidd in Miracle World [A] --> Alex Kidd in Miracle World [Export] Alex Kidd in Miracle World [B] --> Alex Kidd in Miracle World [USA] MEKA 0.62c ---------- - Various fixes. - Added "compatibility list" and "changes list" items in the help menu, allowing you to open them with the internal text viewer. - Released Windows version. MEKA 0.62b ---------- - Sorry for the huge delay in such a minor update. I've tweaked the Z80 core a bit again to fix a little bug that I introduced myself and which puzzled me for a while. I took the occasion also to upgrade to Marat's latest debugger (now showing inline interrupt informations). - Battery backed RAM is now scanned so unnecessary pages are not saved in the .SAV file (this was previously already done, but only inside of save states). - Added new entries to the checksum and compatibility lists. - Updated Spanish localisation. MEKA 0.62 --------- Compatibility notes: - Sonic Blast [GG] minor glitches on title screen in non Japanese mode has been confirmed to appear on a real Game Gear, so the game is now marked as perfectly working. - Thanks to the new 93c46 EEPROM emulator, Game Gear perfect compatibility has now increased to 98.09% (counting like FreezeSMS does, that gives us a whooping 150.00% :) - Statistics: as far as I know, out of the 7 Game Gear games marked as NON-WORKING, 5 games requires a simulation of LCD blurry persistance to show up without flickering, 1 may be severly broken (not possible to complete the game), and 1 is minorly broken. As always, please report if you find out anything you feel as not emulated PERFECTLY: even a single suspicious pixel, etc.. Thank you! - Rewrote 93c46 EEPROM emulation from stratch, it now works and saves data properly. This fixes the following Game Gear games: - Majors Pro Baseball - Nomo's World Series Baseball (J) - Pro Yakyuu GG League (J) - World Series Baseball [A] - World Series Baseball [B] - World Series Baseball 95 - Emulated onboard 64 kb RAM chip of Ernie Els Golf (GG). - For the sake of accuracy, started to implement emulation of the four slighty different VDP chipsets used in Master System 1/2, Game Gear and Megadrive (compatibility mode). They all have subtle differences, causing some games not to work perfectly on all of them. - Fixed glitches in Ys (Japanese version), using 315-5124 VDP emulation. - Fixed bugs in Z80 emulation, letting the Game Over screen for Rambo III to appears normally - and this required many many hours of work! (thanks to Jonas Persson for reporting the bug). Also changed behavior of EI instruction, fixing Double Dragon for Game Gear (again). - Fixed VDP refresh disable emulation for Game Gear. - Fixed YM-2413 state restoring when loading a save with FM playing. - Now store YM-2413 state initialization in VGM files. - If available, store Japanese game name (in romanji form) in VGM files. - Fixed shifted instruction offset in debugger. - Updated TECH.TXT with instructions about how to build a DB-9 adapter to connect SMS Joypads on your PC. - Added full French (by Overture 1928) and Swedish (by Henrik Sankala) localisations. Complete Italian localisation (by Andra Ballandino). - Fixed minor display bug in the Inputs configuration tool. MEKA 0.61 --------- This version may or not have minor glitches on certain games (like, a single pixel or a single blinking row at the top or the bottom of the screen). Please DO report those glitches if you notice any. Thanks! - Moved 104 messages to MEKA.MSG, allowing for full localization of the menus. 99% of MEKA is now localizable. Updated the following languages: English, German, Redneck, Dutch, Portuguese and Spanish. - Improved Z80 core (timing and interrupt emulation bug). - Fixed Rise of the Robots (GG), MEKA being the first emulator to play it without glitches (and even without, it sucks! :) - Fixed most or all (?) glitches in Formula 1 (SMS) two-players mode (maybe not the right way yet). - Fixed Double Dragon (GG) which was not working since an update of the Z80 core (from fMSX) several version ago. - Country changes now immediately takes effects (no need to reset). - Tweaking interrupt emulation for SG-1000/SC-3000/SF-7000 and Coleco Vision drivers. Those changes should not affect anything. - Fixed 'Parallel' video blitter, odd frames were not updated when using the blitter with software 3-D Glasses mode enabled. - Fixed crash of SF-7000 driver when loading a corrupted floppy disk. - Fixed YM-2413 logging in VGM files (Register & Value were reversed!) - Updated SDSC Header support for version 1.01 (adding Author field). - Added Golden Axe theme by Death Adder. (uncomment to use in GUI) - Updated to Allegro WIP 3.9.39 and reapplied all custom patchs. Changed SideWinder autodetection process a bit. Hope it works! - Reduced executable. MEKA 0.60 --------- - Improving timing in Z80 core. - Fixed voices that weren't ok (Alex Kidd: the Lost Stars..). Voices in many many games were tested, finally marked them as 'Ok' in the compatibility list. - Due to timing improvments, now Space Harrier [50 Hz version] has correct glitches (like on a real system) when running in NTSC mode. It is now configured to automatically use PAL/SECAM by default. - Removed the need of specific IPeriod setting for some Codemasters games, meaning that they will now run even if you delete MEKA.NAM. - Added sample accurate VGM logging, allowing to log voices. The option was previously grayed, it is activated now that all voices are Ok. - Updated to VGM version 1.01, to include original TV type information (NTSC or PAL/SECAM) in the file, allowing to play at a different rate. - Fixed minor sprite masking bug affecting scrolling games in certain conditions. Evander Holyfield Boxing (Game Gear) was affected. - Added support for Coleco Vision header/footer in order to load the newly released "Pac Man" and "Dig Dug" ROMs from CGE 2001. - Fixed a minor bug when loading an in-game savestate from the BIOS. - Fixed file loader sorting so that if present, ".." is always on top. - Added/fixed entrys to the checksum and compatibility lists. - Added two Sonic themes by H Hog. (uncomment to use in GUI) MEKA 0.59b ---------- - Fixed vertical scanline counter emulation. - Fixed a minor hardware collision bug introduced in version 0.59. - Fixed usage of '%' in ROM comment field. - Changed message logging (with /LOG) to avoid cutting text in the file when it doesn't fit on the GUI message box. MEKA 0.59 --------- - Various changes to the sound engine: - Fixed PSG Periodic Noise emulation (bass in some Marble Madness tunes, Daffy Duck in Hollywood, and few other games). Thanks Ziria and Maxim! - Added PAL/SECAM machines accurate base clock for PSG wave generation (pitch is around 1% off from NTSC machines). - Added VGM logging. VGM (for Video Game Music) is a new file format recently developed on S8-Dev with collaboration of Dave, Maxim and some other people. Maxim has wrote a WinAMP plugin already. Check out the newly created Music Section on SMS Power at http://www.smspower.org/music ! - Added PSG registers to the technical information window. - Fixed a very weird bug introduced in version 0.58, where a certain sprite configuration and positionning could screws up the whole emulator! This caused problems in Terminator 2: The Judgment Day and Ghouls'n Ghosts. - Added Korean mapper (9) emulation, as used by Dodgeball King. - Added Italian messages translations (by Andrea Ballandino). - Added German messages translations (by Tilman Hesse). - Fixed some PortuguE messages. - Fixed/added accentued characters in some Brazilian game names. - Added new "Mario Must Die" theme, with a nice handdrawn picture :-) - Added new entrys to the checksum and compatibility lists. - Fixed and improved various minor things. MEKA 0.58c ---------- - Fixed the missing soundcard selection menu in some cases. - Added printing of SDSC Header informations when found. The SDSC Header has been defined and created by the SMS Power developement team (based on Eric Quinn's idea) for homebrewn programs. - Drawn Latin-Extended characters (Unicode 0080-00FF) in the big font. Accents are now usable everywhere in MEKA. Be sure to use accents from the Latin-Extended table (usually used by Windows programs, not DOS ones). - Added Spanish messages translations (by Antonio J. Bazalo). - Added PortuguE messages translations (by Rodrigo C. Rubio). - Added "WIP" (Work In Progress) parameter in language definition, to disable warnings and informations when the language is uncomplete. - Squashed one very minor flag bug in the browser when a ROM had an number after a space, at the end of its filename. MEKA 0.58b ---------- - Fixed various minor bugs. - Fixed two scrolling emulation bugs in video mode 5. They did not affect any game, but for the sake of accuracy, better fixing them! - Added Dutch messages translations (by Mark van Tilburg) and Redneck messages translations (by Maxim, using Dialectizer). Fry mah hide! - Added /LOAD command line parameter, to start directly with a savestate loaded (so you can make yourself batchfile loading a certain state.) - Added several new entrys to the checksum and compatibility lists, and fixed some existing ones. Added an USA flag and set the flag to all SMS games only released in USA (Alf, King's Quest, Montezuma's Revenge). - Added one new happy theme from the french movie "Am‚lie Poulain". MEKA 0.58 --------- Again, please report if you notice any bug/glitche with any game, that is not mentionned in the compatibility list. The VDP fix applied in this version is also a massive compatibility test, and I would like to know if it has any unexpected behavior on other games. So play, play, play! :) - Added PSG sound logging to WAV files, accessible from the Sound menu. - Rewrote messaging system, added localization support. Moved all messages to an external file, MEKA.MSG. You can now change 80% of the texts used in MEKA, and translate it to the language of your choice. I am however NOT YET sure about how accents will work, since it depends on the font used. This feature required a pass on all existing code and so took plenty of time to do (10+ hours), I might have screwed a few messages during the change, so be sure to send me an e-mail if you notice anything unusual. - Implemented a VDP quirk found in Master System 2 but not Master System 1 or Game Gear, discovered by Charles Mac Donald (thanks Charles!). This one fixes Cosmic Spacehead *BUT* might screws up few other games. I did a bit of testing but couldn't do them all again, so please report if you notice anything unusual with another game. - Improved hardware sprite collision accuracy, fixed a bug in some cases where it was previously framerate dependant, and rewrote the whole code in assembly. - Changed initializations messages and some other messages. - Fixed an incorrect numbers of TV lines in PAL/SECAM TV emulation (due to a typo - thanks goes to cgfm2 for pointing me this stupid error!), allowing removal of a few custom MEKA.NAM parameters (Daffy Duck in Hollywood..). - Fixed the annoying bug that caused crashes on startup under DOS when sound was enabled. - Fixed a minor bug in Codemaster mapper emulation, that affected the checksum check of 'Drop Zone' (although the game worked). - Fixed crash when using a patch defined in MEKA.PAT that write outside of any existing data. - Added (very) quick and (very) dirty frame-per-frame advance by pressing ALT-F12. In fact, it will unpause the game then pause it back next frame. - Updated Colecovision compatibility list and added some product IDs, thanks to Tincho DJ. The current state with Colecovision games is: a mess :( Someone will lots of Colecovision knowledge would be very helpful to help sorting out all bad dumps, testing games and redumping others. MEKA 0.57b ---------- Lots of fixes, for a total of twenty working hours. Please also note in documentation that *I HAVE MOVED HOUSE*, that is in case you planned to send something. - Various minor fixes and improvements. - Fixed startup delay (and sometimes crash) when autodetecting Sidewinders. - Fixed and improved the new dynamic palette handler, avoiding palettes overflow on some Game Gear games such as Sonic & Tails 2 / Triple Trouble, Sonic 1 or Deep Duck Trouble. The fourth level of Sonic 1 is however not yet perfect when both air and water are shown on screen. Thanks to ICEknight for pointing the bug out. - Made various clean and corrections to the main sound engine structure. It should not have broken anything, but please report if you notice something unusual. Noticable changes are that: - MEKA refuse to start if sound initialization has failed. - Sound is now muted while certain long operations are being processed. - Sound card type is not lost if you only disable sound. - An incorrect BLASTER environnement variable is now reported. - Added an algorithm to automatically detect certain mappers and select them when the ROM is unknown. - Fixed vertical scrolling emulation in certain special cases. - Fixed zoomed sprites in SMS/GG video mode. They were accidentally screwed up by a typo (!) in previous version, and affected Virtua Fighter Mini. - Fixed a bug with checksum handling. In some cases, ROMs with only a few different bytes were previously not recognized as different. - Fixed usage of the ';' key in the input system (now usable), previously the character was considered as beginning a comment in MEKA.INP. - Fullscreen messages are now correctly displayed when the current emulated system uses a resolution higher than your fullscreen resolution. - Fixed debugger breakpoint when loading a save state. - Added some new entrys to the checksum and compatibility lists, and fixed few existing ones. Added a french flag, currently used for games translated in french. MEKA 0.57 --------- Note: I made lots of little sources changes in this version. Things have been tested, but in case you notice anything unusual, please contact me. - Rewrote dynamic palette handler, minimizing actual hardware palette changes, reducing snow and generally reducing flickering when games were abusing of palette changes (like the "Happy Birthday" demo, or some Game Gear games). Due to that change, Palette and Tile viewers are now slighty slower than before, but since they are not used for playing, it is fine. - Rewrote hardware sprites collision emulation a more accurate way, fixing Cheese Catastrophe (SMS) bonus catching. There was an easy way to get it to work, but technically speaking, it was not the right one. Instead I emulated the feature a better way so that theorically, any tricky uses of it should be working. Speed might have dropped of about 1 FPS on slow computers. (Thanks to nop.nop for the bug report.) - Added data dumping facilities for developers and hackers. You can now dump the following to a file: - RAM (raw or text hex/ascii) - VRAM (raw or text hex/ascii) - Palette (raw or text colors definitions) - Sprites (raw or text sprites definition) - VDP Regs (raw or text binary/hex) - OnBoard Memory (raw or text hew/ascii) Those functionnalities are available by starting MEKA with /DEBUG. - Added Sega Keyboard (SK-1100) hardware detection emulation. You can know use the emulated keyboard to play SG-1000 (and early SMS) games supporting it. - Added a 'none' value for joypad driver, to disable any kind of detection (as it may be slow on some computers). See MEKA.INP. - Battery backed RAM optional pages are now not saved when their content is null. - Optimized the technical information viewer that was previously too slow. Also made cosmetic changes to the informations shown. - Fixed error message that said MEKA was unable to write SaveRAM to write, while it did correctly. - Fixed savestate loading bug in some very specific cases when using a custom mapper. - Fixed sprite drawing in overscan video mode. - The selected tile in the tile viewer is now refreshed if modified. - Fixed PSG volume bug, where volumes 14 and 15 were actually the same. (thanks to Martin Konrad for noticing it) - Changed the 'palette_bright' option to a 'palette' option that can be either 'muted' or 'bright', the later being now the default, since many people suggested that it was better than the old default one. Also added a switch in the GUI options box to change it dynamically. - VSync is now automatically avoided if a speed faster than 70 hz is being used. So you can use a blitter with VSync enabled and still profit of accelerations if you want them sometimes (skip intros, etc..). - Partially rewrote popup menu code. Also hacked a bit to fixed the bug when more than 32 themes were enabled on the same time. - Added the usual amount of new themes and new database entries. - Added some new comments to the configuration file. - Converted all ASM code to NASM format, for better portability. - Ported MEKA to Windows. Cool. MEKA 0.56 --------- - Added Sega Super Control Station emulation, codename SF-7000. The SF-7000 is a rare addon for the Sega Computer 3000, providing it with a 3" Floppy Disk Drive, 64 kbytes of RAM, a parallel printer port and a RS-232C port. The later two are only partially emulated as anyway there is no way to use the emulated connection (ex: for printing) yet. Many thanks goes to Marc Le Douarain for his help and dumps of his old disks, and Ulrich Cordes for the FDC-765 emulation (see documentation). I added in the documentation a paragraph about how to use SC-3000 and SF-7000 Basic software, as it is needed to load programs for the later. Also, I am still looking for a real SF-7000 and any softwares! - Added sprite flickering emulation in video mode 5 (SMS/GG), and interfaced so you can now enable it if you feel like playing shooters with invisible bullets. It is available in the VIDEO->FLICKERING menu. - MEKA is now ignoring those rarely present 64 bytes footers. - Fixed Ninja Gaiden (GG version) hand on intermission animation. - Fixed PAUSE button which was broken in version 0.55b. - Fixed blinking sides when a program was using text mode (Sega Basic, ..) with a border color different than black. - Fixed Sega Keyboard letters color. - Fixed /LOG command line option which was ignoring the given filename. - Added and fixed entrys in the compatibility and checksum lists. - Various minor changes - changed messages, fixed typos.. MEKA 0.55b ---------- - Added configurable mouse speed values in the MEKA.INP file. - Fixed mouse under Windows NT / Windows 2000. MEKA 0.55 --------- - Added builtin documentation, accessible from the "HELP" menu. - Entirely revamped the input system. I originally fixed Paddle Control emulation then noticed the problem I was having with Super Racing was due to a bug in the original game. I did not feel like adding a cheap hack and beside it was time to clean it up, I just needed a reason :) Inputs related changes you will notice are: - Added configuration tool, showing small pictures of peripherals being used (hope you like the pictures, as I spent a long time drawing them). This tool allows you to see currently available inputs sources, enable/disable them, and change their key/buttons mapping. No more dealing with obscure scancodes numbers (finally). To keep going with the MEKA tradition, every configuration bit is stored in a human-readable and manually editable file: MEKA.INP. You can access most of the functionnalities from under the interface but experienced users might want to check this file out. The new input system is high-level oriented and allows you to do many nice things like playing with two pads on the same time or mapping pause to a mouse button. Whatever you feel. - Any joypad/joystick corresponding to the driver selected in MEKA.INP should be automatically enabled on starting, and available for use. - Renamed left occurences of peripherals that were incorrectly named (Paddle Controller -> Paddle Control, Light Gun -> Light Phaser) - Improved Paddle Control emulation so that they will work in Japanese mode, and allowing Super Racing to detect a paddle when plugged on, instead of the regular joypad. - Fixed a precision bug in Paddle Control 2 emulation. - Added support for a second Sport Pad / Trackball. - Added digital input source emulation with the mouse, so basically you can play any joypad game with a mouse now. Expect being really frustrated with most games, but it is actually very cool for shooters and games where you do not have to do 'long' movements. Try R-Type. - Added 3-D Glasses emulation, with both software and hardware modes: - Software mode let you play 3-D games by showing only images of a choosen side (left or right). - Hardware mode supports REAL Sega 3-D Glasses connected on your PC through the communication port! See TECH.TXT for more informations about how to build a Sega 3-D Glasses adapter and enjoy a new dimension of videogaming :-) Warning: 3-D Glasses support through the COM port is still not in perfect stage, meaning that you may experience flickering. A blitter with VSync enabled is *strongly* recommended. Also stop playing every 30 minutes eyes you'll become blind :) - Tweaked VDP code for potentially more accurate side effect emulation. - Fixed sprite collisions in certain cases. The following Colecovision games are now perfectly playable: - Carnival (Bonus Level is ok) - Jumpman Junior (Ladders on level 3 are ok). - Pitfall 2 (No false hit on the third screen). - Venture. Thanks goes to the one who sent me a long e-mail about collision detection some months ago, but which I unfortunately lost and was then unable to answer. E-mail me if you are still around :) - Fixed hard pausing. You can now safely take screenshots after pausing with a message shown on the screen, as it will not be shown in the shot. - Fixed loading of very small ROMs, which affected Tic Tac Toe on Colecovision, and maybe your very own demos programs. - Implemented Antiriad's hack to Allegro - used in Raine - to permit usage of Sidewinders while their driver is loaded (not tested). Thanks! - Fixed the Eagle blitter which was not centered and showed garbage in some machines. Also fixed the default Eagle blitter configuration which limited speed to 30 FPS even on a very fast system. What a loss! By the way, Eagle does in fact looks nice with a few games. Try R-Type. - Slighty optimized memory accesses and tile refresh. - Changed the key to save screenshots from F12 to PrintScreen. If you are using Windows, be sure to configure the properties of your DOS box to enable the use of the PrintScreen key if you want to make screenshots. - Added F12 shortcut to hard pause emulation. - Added access to enabling/disable GUI Vertical Sync in the options box. - Fixed a bug that prevented Battery Backed RAM or EEPROM to be saved when freeing ROM. - Added a technical document (TECH.TXT) with basis informations about the systems, as well as the schematic for the 3-D Glasses adapter. - Reduced default FM writing delay, that should speed up the two games over-abusing of FM writes. Try R-Type title screen. - Added various name and checksum entries, and corrected many existing ones. Should have noted out all Game Gear games running in Master System mode, fixed some Colecovision names and date, and generally improved accuracy. Thanks goes to Maxim and Luke2 for their precious help! :) - Added Korean flag in the file loader and associated Super Tetris with it. There are still several Korean games to dump, however. - Fixed leap year calculation (for display of dates). - Fixed a crashing bug when passing too many parameters on command line. - Added the usual bunch of new GUI themes, and more pictures are available from the homepage. - Plenty of minor fixes here and here. MEKA 0.54b ---------- - Made some very minor fixes. - Added two new themes (Deep Purple and Deep Brown). MEKA 0.54 --------- - Updated to the documentation, improved many parts and added new things. Please read it! - Fixed invalid vertical sprite wrapping in video mode 2 (bug introduced in version 0.51, slighty affecting The Castle and maybe other games). - Added PSG wave synthesis sound rate setting in the configuration file. Rate is no more fixed to a weird value like in all previous versions, avoiding the clicks and noise with certains soundcards. You can also change the rate to the default values of 11025, 22050 and 44100 Hz from the GUI pop-up menus. - Added separate PSG channel enabling/disabling. Mainly useful for musicians who want to listen to different channels separately, but it is also very fun to disable some channels and play games with somewhat new musics :) - Fixed FM bug when hard pausing and unpausing in some games. - Addams Family, Operation Wolf and Sonic Blast now automatically run in PAL/Secam mode when NTSC is selected, due to the games having bugs in NTSC mode. - Fixed the badly positionned line of Hang On in Hang On / Safari Hunt. - If brutally forced to close (like when switching to a blitter using an invalid resolution), MEKA now switch back to its starting directory. - Added screenshot filename template to the configuration file. You can now configure weither you want padding, short or long filenames, etc.. Also changed screenshot numbering starting value from 0 to 1. - Added "integer stretched" display of the themes background pictures (see MEKA.THM). - Added new themes, some of them using nice background pictures you are invited to download at http://www.smspower.org/meka/themes. MEKA 0.53c ---------- Game Gear compatibility rate is now of 95.80%. It is the only unperfect system and that's mainly due to the lack of LCD screen persistence of vision emulation. - Kishin Douji Zenki very minor graphic bug was a bug in the game itself, not in MEKA. Thanks goes to Adol brothers for their help on this one. - Added a patch to fix a bug in Walter Payton Football (in the game itself) preventing it to works on machines with a FM Chipset. - Fixed Wanted patch, I had accidentally commented a line out. - Fixed California Games 2 minor graphic bug when selecting the top left entry of the menu (screwed in version 0.52). Thanks Pieter! - Added new entries to checksum and compatibility list. MEKA 0.53b ---------- I finally figured out what was the problem of the major slow down in some video modes when page flipping was enabled. Actually using page flipping need to force vertical synchronisation in most video modes, so enabling them both will make the program synchronise twice per frame to the vertical refresh, causing speed to be limited to about 30/35 FPS. The default blitter definition files now have Page Flipping modes enabled by mode, replacing the obsolote VSync modes. - Fixed a bug preventing files to appear in the file browser under DOS. - Added all known Colecovision dumps to the checksum/names list. Names are based on Cowering's GoodColeco utility. - Game name is now dynamically updated under the GUI is a country change affect the current name. - Fixed "Rise of the Robots" by forcing NTSC mode when it is not enabled. - Added a patch to fix a bug in Wanted (in the game itself) preventing it to works on machines with a FM Chipset. - Fixed a bug sometimes happening where disabling background layer display wouldn't work. - Added 5 new themes (commented by default). MEKA 0.53 --------- Master System compatibility rate has now reached the perfect 100.00% assuming out of the 373 tested ROMs none was broken in a recent version. Something major have changed in this version and which might screw just about any game. So if you find anything unusual that might be a bug, please report it to me. As soon as possible I'll spend a week trying all games again. Enabling page flipping is known to cut down the speed by a factor of two. This is obviously a bug as page flipping should not affect performances so at the moment I suggest avoiding it and enabling VSync instead. As a side news, I have ported MEKA to FreeBSD/NetBSD. It probably compiles under Linux also, and whenever I can get my hands on a computer running Windows applications at a correct speed, a Windows port will be worked on. - Fixed temporary sound bug when loading savestates in certains cases. - Added TV Type switch to change between NTSC and PAL/SECAM. - Improved tile viewer so that a click on a tile shows its number and the tile itself. Might be useful for developers and ROM hackers. - Improved file browser: added a "Reload Directory" button and a "Load Names" button to load full game names for all files. - Fixed Y's (SMS/J). - Added full TV Oekaki Graphic Board and Pen emulation, using mouse. Button 1 simulate a pen press and button 2 simulates the pen being away of the graphic board - when it is away you can use standard inputs. Now you will be able to draw with the emulator ^_^ Thanks to Toshi for sending out the Graphic Board. - Fixed GP Rider (GG) road corruption. - Fixed NBA Action (GG) abnormal flickering. - Fixed NBA Jam TE (GG, previously unknown bug) and Surfs Ninja (GG). - Fixed reset key in Sega Keyboard emulation. - Fixed Gear Game communication port emulation somewhat broken in previous version and which affected Pac Attack. - Fixed secret games left side of the screen bug in fullscreen mode. - Improved auto frame skipper synchronization to the choosen speed. - Compiled with the newest patched Seal Audio Library, improving overall sound quality (16-bit mode was somewhat useless in previous versions), and ALLOWING SOUND TO WORK ON SOUND BLASTER 128 SOUND CARDS, finally. A big thanks goes to whoever patched Seal for that. (I guess it is someone to the MAME team, but I am not sure.) - File browser now go in the root of drive if current directory is invalid. - Removed a broken line in the MEKA.NAM file causing Back to the Future 3 to show a black screen. - Added even more new entries in the compatibility and checksum lists. - Lot of sources changes and improvments. MEKA 0.52 --------- Compatibility rates as of version 0.52: Master System: 99.72% (not perfect because of the Japanese version of Ys). Sega Game 1000: 100.00% Sega Computer 3000: 100.00% (excluding emulation of optional peripherals such as the Sega Printer) Game Gear: 95.03% (excluding gear-to-gear emulation used by certains two players games) - Fixed the minor glitches in: - Back to the Future 2 (black section flickering between the road and status bar) - Gangster Town (little line of skyblue pixels on the top of the car in the first scene) - Operation Wolf (minor graphic glitches on the top of the bottom bar when shooting) Tested Wonderboy in Monsterworld on a real system and confirmed the minor glitch when the menu is vertically scrolling is a bug in the game itself. Did some research about Ys (J/FM), with help from Toshi. It is not considered anymore as a bad dump. The bug happening in MEKA also happens when using a real Game Gear or a Megadrive with an adapter. However the game show a perfect status bar on a Japanese Master System, so the bad behavior is considered as a bug of MEKA, even if in the first place it is due to a bug in the game code taking advantage of an odd behavior of the Japanese Master System. Also: - Improved run-time TMS9918 video mode detection. - Fixed Hyper Pro Yakyuu 92 (GG). - Reduced flickers in NBA Action (GG). - Fixed freezing until a key is pressed when loading the Japanese BIOS. - Fixed yet another silly bug introduced in previous version and screwing some SC-3000 software such as the Sega Basic. - Added new entries to compatibility and checksum lists. Also redone SC-3000 list with names corrections for Japanese educational softwares. - Fixed potential VDP bug - wasn't affecting any games, but could have. - Implemented MAME Z80 CPU Core but did not enabled it in the public version as it doesnt bring anything better than Marat's core: they are on par, but MAME license is quite limiting. - Improved documentation inside of the MEKA.BLT file. - Fixed a bunch of minor bugs. Fixed handing of ROM smaller than eight kilobytes. Fixed empty entry creation in the VFN database. Fixed a bug in windows repositionning when changing resolution. - Reduced executable size. And also: - Added background picture caching for a faster switch to the GUI when a big image is used on background. - Added a bunch of new themes into the distribution package. Background pictures for some of the themes are available on a new site at http://www.emucamp.com/meka/themes - As of now the PICS/ directory should be considered as the one everyone have to use to share themes easily. You can still have your own themes pictures stored anyway, anyway. MEKA 0.51 - OverClocked Edition ------------------------------- SG-1000 perfect compatibility rate is now of 100% - Added the possibility of adding a custom background picture in themes. Keyword to be used in MEKA.THM is "background_pic". Pictures need to be in PCX format and a maximum of 128 colors will be used. You can zoom, tile or center the picture using the appropriate keywords. - Added desktop saving. Active windows and their position are now saved and restored back when loading MEKA. - Rewrote sprite engine for video modes 1/2/3, fixing the minor bug in Pitfall 2 (SG-1000) and Rockn'Bolt (SG-1000). Probably also fixed some Colecovision games. Added optional flickering emulation. MEKA 0.50 --------- Master System perfect compatibility rate is now of 98.90% Games still causing problems are: Back to the Future 2 (black section flickering between the road and status bar) Gangster Town (little line of skyblue pixels on the top of the car in the first scene) Operation Wolf (minor graphic glitches on the top of the bottom bar when shooting) Wonderboy in Monsterworld (minor glitche on the menu vertical scrolling line when pressing pause) Found out that the bug in Aerial Assault was happening on a real system. So it's not considered as a bug anymore. Next step will be to improve Game Gear perfect compatibility rate (94% now). First, reparing bugs introduced in MEKA 0.40: - Fixed accidentally left bug in SG-1000 interrupt emulation, fixing Championship Lode Runner and probably other games. - Fixed accidentally left minor scrolling bug in a few games (Castle of Illusion to name one. I forgot about the others). New stuff being: - Rewrote Light Phaser emulation. The following games are now playable: - Laser Ghost (Light Phaser is optional) - Missile Defense 3D - Operation Wolf - Shooting Gallery - Wanted - Improved various bit of emulation to fix the following games: - Robocop 3 (SMS): does not crash anymore when pausing. - Back to the Future 3 (SMS): have minor title screen bug fixed. - Sonic Drift 2 (GG): bottom of screen is correct now. - Out Run (GG): music now plays. - Added Game Gear vertical scrolling lock emulation (fixing Fray). - Added wide effective area emulation (2 Star Trek games on Game Gear). - Implemented better systems hardware differences to allow detection. Renaming Pit Pot (SMS) to the .SG extension and running it will now show a custom error screen! Thanks goes to Yujiro to the notice. - Slighty optimized Master System and Game Gear screen refresh. - Rewrote blitters handling system: - Added blitters definition file (MEKA.BLT) where you can configure fullscreen video modes drivers, resolution and effects, and create your own video modes this way. - Added "TV Mode" blitter that simulate accurates TV scanlines. - Added "Double" blitter. Nice uses of it are: - Doubling screen with 512x384 mode (getting true Fullscreen). - Doubling screen in a tweaked mode (Game Gear with big pixels). If you find any suitable mode for Game Gear other than the ones listed in the MEKA.BLT file, please tell me about it. - Added "Page Flipping" option to blitter (reducing flickers) - Included "Perfect" blitter definition with all best features enabled (512x384 resolution, TV Mode, Doubled Fullscreen, Page Flipping and Vertical Synchronisation) for people with *very* fast computer. - Removed hotkeys to enable/disable the Scanlines, Eagle and Parallel effects. They are now part of blitters configuration. The current blitter can be changed by pressing F1. - Rewrote frameskip handling system and added speed throttling. - F2 key now switch between standard and automatic frameskipping. - F3 decrease speed in automatic mode, else decrease frameskip. - F4 increase speed in automatic mode, else increase frameskip. - Added icons package from various contributors (see ICONS.ZIP). - Added Massage savegame converter. Rename a .MSD file in the MEKA naming convention and it will be automatically converted when loading. You might in some cases experience sound or various other problems with certain games. The usual solution is to pause and unpause the game, else try to change screen/level. - Slighty improved voice emulation. - Rewrote drivers handling system. It is easier to maintain internally now. - Color related stuff: - Fixed potentiel palette problems with some video card/mode couples. - Revamped whole palette update handling (reducing snow). - Palette viewer now show no more than the correct number of colors in SG-1000/SC-3000/Coleco mode. - Fixed configuration file problem when using PSX and N64 joypads. - Added new games and product numbers to compatibility and checksum lists. - Added mouse button 2 shortcut to switch between the two Light Phasers. - Added some new GUI themes - uncomment in MEKA.THM file to use them. - Fixed file browser bug when overwriting recognized ROMs with unknown ones would keep the old, recognized name showing. - Fullscreen captures now ignore status message and filters/effects. - Made some structural optimisations, increasing speed of a few percents. - Fixed bug virtual longfile name self created list saving. - Fixed a screenshot naming bug with short ROM names. - Fixed rare crashing bug with the blood cursor GUI effect. - Sega Basic Level 3 Version 1.1 Japanese now works with a patch. - Reduced savegame size for SG-1000 and Colecovision systems. - Compiled with latest Allegro library, adding support for the following joysticks/pads drivers: - DB9 pads through parallel ports (allow to plug real SMS pads!) - PC Engine pads through parallel ports - Saturn pads with IF-SEGA interface cards for PC. Now Phantasy Star runs at 49 frame per seconds on my computer ! MEKA 0.40 --------- Master System perfect compatibility rate is now of 97.78% Games still causing problems are: Aerial Assault (minor scrolling glitch on the beginning of a level) Back to the Future 3 (minor bug on title screen) Missile Defense 3D (buggy lightgun emulation) Operation Wolf (buggy lightgun emulation) Robocop 3 (pausing crashes the game) Shooting Gallery (buggy lightgun emulation) Wanted (buggy lightgun emulation) Wonderboy in Monsterworld (glitches when pressing pause) Game Gear perfect compatibility rate is 94.55% 17 games are still causing problems, including 5 which requires simulation of LCD screen visual persistance to produces transparency effect, 3 using an internal EEPROM to save custom teams, 2 having bad scrolling positions, and the 7 others: GP Rider (road distort itself after a moment) Kishin Douji Zenki (one line of clouds is not scrolling in fighting level) NBA Action (sprites flickering, might be the real game behavior) Out Run (no music for some reasons) RBI Baseball '94 (sprites not visible in top view, might be a bad dump) Sonic Blast / G-Sonic (micro title bug in US/Euro mode) Sonic Drift 2 (bottom line has a bad scrolling offset) Sega Game 1000 perfect compatibility rate is 97.40% Games still causing problems are: Pitfall 2 (minor glitch at the top when dying) Rockn' Bolt (sprite priorities bug on lift when starting) - Improved emulation on various point, fixing: - Altered Beast (SMS): title screen effect is now ok - Cool Spot (SMS): no more minor flickering - Evander Holyfield Boxing (GG): no more blue screen every odd frame - Global Gladiator (SMS): no more minor flickering - Gun Star Heroes (GG): no more glitches here and here - Hang On / Safari Hunt (SMS): fixed a bug preventing to start sometimes - Heavy Weight Champ (SMS): music play on introduction - Hurricanes (GG): no more blue screen every odd frame - Impossible Mission (SMS): room are showing properly when entering - NBA Jam (GG): playfield is ok - PGA Tour Golf (SMS): playfield is ok before game start - Legend of Illusion (SMS): does not hang anymore at the sunken ship stage - Out Run (GG): no more flickering - Orguss (SG-1000): no hang when exploding with the small robot - Safari Hunting (SG-1000): no hang when entering in the game area - Safari Race (SG-1000): better response of button on title screen - Shining Force 1 (GG): fixed random crashes - Shining Force 2 (GG): fixed random crashes - Shining Force 3 (GG): fixed random crashes - Speedball 2 (SMS): no more flickering - Sonic Drift (GG): now works perfectly - Sonic Drift 2 (GG): now works almost perfectly, minor bug on bottom - Terminator 2: Judgement Day (GG): no more blackout every odd frame - WWF Steel Cage Challenge (SMS): no more moving bug on barriers - Xenon 2 (SMS): no more flickering - Custom IPeriod values for Aerial Assault (SMS), Barcelona 92 (SMS), Gokuaku Doumei Dump Matsumoto (SMS) and Pro Wrestling (SMS) are not needed anymore due to improved emulation, and were removed. The only game left needing a custom IPeriod value is "Shadow of Beast" which sometimes crash on title screen with the default value. - Improved voice emulation, many games sound correct now (not all). - Updated to Allegro WIP in prevision to future improvments. In the meanwhile, the new version provides drivers for Gravis Grip, PSX and Nintendo 64 joypads, as well as better Sidewinder support (untested). - Rewrote hardware sprite collision emulation. Might break some games, please report if you discover anything unusual! - Improved Master System Sportpad controller emulation. Games are easier to play now, even if it is not perfect. - Improved default mapper emulation. - Added (buggy) EEPROM model 93c46 emulation. This chipset is used by three Game Gear baseball games to save custom teams and game progress. Pretty though one to emulate, but that's the only way to reach perfect emulation ^_^ - Added Rapid Fire emulation. - Improved video mode 2 emulation, fixing Cosmo Fighter 2 (Coleco). - Added video mode 3 emulation, used by two painting programs for the Colecovision, and very probably by many SC-3000 programs. - Definitively removed the snow effect that pissed everyone :-( I would have stopped on the 28 of December, anyway. Instead, added the "special=snow" parameter in the theme file, to create your own themes using that effect. - Added Christmas and Sunrise GUI themes. - Compatibility and checksum lists changes: - Added a bunch of new names. - Added new Game Gear Japanese games (thanks to Casiopea). - Differencied names for alternate versions (thanks to Luke). - Added product numbers for about 150 Japanese Game Gear games. - Added IPERIOD_SG1000_SC3000 setting in the configuration file. - Added a patch to fix the bug in Sport Pad Soccer which make it hang on systems without the FM chipset. - Fixed bad screen size bug in certain cases after freeing ROM. - Added improved filter for old configuration file.

MEKA 0.31 --------- (YM-2413 emulation is disabled by default because of many people who do not know about the existence of that chipset and complain about the musics and sound effects not being the same as they used to hear. Now that you know about it, feel free to enable YM-2413 emulation yourself). - Updated various chapters of the documentation. Please read it! - Added ZIP files support. Also improved file handling in general. Warning: loading ZIP files which do not contains valid ROM images may crash the program when it comes to emulating a non Z80-code file. - Made some minor optimizations of screen refresh. - Fixed a bug that caused games not to run before being reseted when in Japanese mode with the BIOS enabled. - Fixed a bug which cause the START button to be randomly pressed just after loading a Game Gear savegame. - Added a patch to fix the bug in American Pro Football that make it hang on systems with the FM chipset. - Fixed too early palette setting when loading a SG-1000/SC-3000/Coleco game from the command line. - Added support for sprites both doubled and zoomed. - Added options box with various flags modifiable directly under the GUI: - Enable/disable startup BIOS logo. - Keep file browser open after loading game. - Switch to fullscreen mode after loading game (new option). - Enable/disable virtual long file names (new option). - Enable/disable messages in fullscreen mode. - Slighty improved dynamic palette system, fixing Moldorian and other games, until a better fix could be applied. - Added an option to show games product numbers. - Game comments are now displayed under the GUI, and a warning is given on known bad dumps.

MEKA 0.20 --------- - Removed delays when accessing to soundblaster hardware registers, resulting in a 20 frame per seconds speedup in R-Type, and no more slowdowns in Wonderboy 3 with YM2413 emulation enabled. If you have problems with this version, try setting the value back to 16 in the configuration file, and be sure to contact me. - Added automatic peripheral type switching. - Added Sport Pad controller emulation. - Improved Paddle controller emulation (much more precise). - Finally managed to understand peripheral detection, so you can play Out Run with the Paddle controller enabled (ala Steering Wheel) for the first time in your life :-) - Fixed Light Phaser emulation bug in Operation Wolf. - Added a switch to enable/disable YM-2413 emulation inside of the GUI. - Added a switch to change country inside of the GUI. - Emusphere.com sucks (just checking if they ever read what they paste). - Messages are now shown in fullscreen mode, making things a bit slower. You can disable that feature in the configuration file. - Fixed snow when VSync is enabled and colors are being updated. Check the Star Wars introduction to notice the difference. (thanks to Lord_B). - Major checksum, name and compatibility lists update. Added more than 200 new entries, fixed some names, and added more product numbers and Japanese name equivalents.

Uncomment them in the default theme file or enable them with Wonder Theme. - Updated savegame format (backward compatible, of course). - Increased end delay for non registered users. - A few other cosmetic changes. Special thanks for this release goes to James McKay for having figured the big part of the controller thing by originally hacking Sport Pad Football. MEKA 0.13.1 ----------- - Fixed many crashing bug introduced in version 0.13. - Fixed FM persistant sound when loading a PSG game after a FM game. - Fixed a bug when trying to free a ROM when the BIOS logo is running. - Now you can load a savegame while the BIOS logo is running. - Fixed Shining Force 3 (Game Gear). - Added some more entries in the compatibility and checksum lists. MEKA 0.13 --------- - Various non emulation bug fixed. - Added an option to free the current loaded ROM (to play the snail game). - Added Colecovision emulation. - Color themes are no more hardcored into the executable, so you can create your own ones by editing the MEKA.THM file. Added the following new ones: - Girl's Power (by me) - Monochrome (by Limbs a Flyin') - Necro (by Roni) - Grey Box (by Puyolin and me) - Added the necessary code for handling registration keys. Now registered users have a permanent keyfile that unlock MEKA. - All pause buttons bug with or without joypads enabled should be fixed now, although I still cannot test the code. - Fixed snow in SG-1000/SC-3000/Colecovision games. - Fixed a keyboard lock bug that happened sometimes (mainly when starting "BrAin waSH" but also in some other cases). - Update savegame file format. Old files can still be loaded with this version, but you won't be able to play the new savegames with an older version. Oh well, who cares ? - Removed SMS background picture anti-aliasing to fit with all color themes and added a picture when no cartridges is inserted. - Some optimizations in SG-1000/SC-3000/Colecovision games. - Added FM patch for Monica Em: O Resgate. - Added a few more titles to the compatibility and checksum lists.
