A new MEKA 2007-04-26 snapshot is available:
http://www.smspower.org/meka/wip/

Please please, people, harass me so I can finish a proper 0.72 release. Need to fix "TV mode" blitter among other things..

- 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]
- Tilemap viewer:
- Fixed leftover of white rectangle when mouse hover last line. [Omar]
- Debugger:
- Added "B nopnop" shortcut to break on two successives NOP instructions.
This is basically equivalent to "B x =0,0". [Omar]
- Miscellaenous:
- 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.
- Added and modified entries in the checksum and compatibility lists. [Omar]

The build date in the About box says 2006/11/30
Is this accurate?

It's my build system, doesn't always update the date, my fault. It's indeed a build I made yesterday (I'll try to fix it).

Are you going to fix correct handling of IFF1 & IFF2 on NMI soon? =)

Pause test

It's not high priority but I'll try to. On another hand, I'd rather try to avoid tweaking emulation and release a stable 0.72 then get back to messing with emulation stuff (this included). But thanks for the test and past infos.

Applied STFUADI, fixed and commited.
http://svn.smspower.org/listing.php?repname=MEKA&path=%2F&rev=51&sc=...

I saw that screenshots being taken without 8 columns (248x192) are an already noted issue. Running games which use sidescrolling with the techinical info window turned on, I saw that there is a LeftColumnBlank variable set 1. Games which don't use it (like Zaxxon 3D, for instance), have that variable set 0. I guess that's just a metter of setting that variable 0 or 1 to let the shots come out in the right resolution (256x192), but I couldn't find anywhere to change it (nor in the GUI, neither in the configuration files).

Note that I don't know a thing about development, so maybe what I'm saying here is complete bullshit. But if it isn't, could that be fixed for the next release?

What problem are you referring to ?

There's something I wrote at the very top of TODO.txt :

Quote

SMS screenshots always 256x192, not 248x192?

But frankly I don't remember why, and I can't reproduce the problem. The thing is that is the left column is cleared, MEKA crop the screenshot to 248x192. Is that a behavior you dislike?

Exactly, Bock. I know that the left column is pretty useless, and if it isn't cropped, it will just show a black column, but the fact is that I contribute a lot to MobyGames, and the site's policy is to have SMS screenshots at its original resolution 256x196. I'd like to have an option to turn the "auto-crop" feature off, if possible.

But it's totally meaningless, keeping that left column makes as much sense as including the top and bottom borders too. How do they deal with the various resolutions Mega Drive games have, especially the ones with non-square pixels? The left column blanking is effectively a resolution switch as much as the extra-height modes, albeit one that doesn't make the screen flicker or blank when it's applied.

Well, the accepted resolutions for the Mega Drive are 256x224 (32Hx28V),
320x224 (40Hx28V), 256x240 (32Hx30V, PAL only) and 320x240 (40Hx30V, PAL only).

Anyway, I just asked that 'cause I use MEKA a lot, but when it comes to taking screenshots, I have to use another emulator, but just because of that. :/
