R-Type for the Master System doesn't always seem to work on a Mega Drive I (PAL) with the Master System Converter.
I literally cannot figure out how it sometimes works and then doesn't for ages. I can ALWAYS get it to work by turning the system on and THEN putting the game in and resetting, but that's surely not healthy... Nowhere else on the internet mentions this. Funnily enough, it apparently struggles when on a flash cart too, as I asked around on a SEGA forum once. |

R-Type works fine on my Everdrive and I've just tested a PAL cartridge on an MS adaptor in a PAL Model 1 Mega Drive and it works fine.
I'm thinking your problem with the MS adaptor sounds more like a need to clean contacts. |

In case that somebody is documenting Mega Drive compatibility as well, I can confirm that The Addams Family doesn't boot at all on a Japanese MD. |

Anyone have a suggestion for my Fantastic Dizzy dancing pixels problem as above? | |
|

The game uses a different palette for the status bar than for the game screen. It writes to the palette during rendering of that line. These writes cause the written color to get visible. For another game showing the similar artifacts check this thread out: www.smspower.org/forums/14855-GunstarHeroesGGSpriteFlicker This phenomenon is also know as "snow effect". Searching the forum for this term you might also find more information on it. |

This effect doesn't appear on emulators or on videos on youtube that were directly recorded from a Master System, so I'm curious if this is a problem limited to the model 1 console. | |

Those pixels are CRAM access dots, each time a color is written it is show on screen as the CRAM is single port. Write cannot be delayed and reads happen all time so the write takes precedence and the renderer shows the data being written to the CRAM on screen druing the color fetch.
Emulators don't emulate this behaviour. |

Not quite right, you can setup Emulicious to emulate it. :) |

Maybe some of the PAL games should be edited to clarify if the glitching is minor or major? I played Sonic 2 on a US SMS and didn't find the graphical glitching to be any worse than the glitching in US NES games like Mega Man 3 and Duck Tales. It's still 100% playable. Some of those games listed under PAL are also Brazilian games, which use a 60 Hz PAL standard, so the issue with the game may not be related to PAL/NTSC. | |

Monopoly added.
It doesn't work with a Mega Drive + Power Base converter. Only the title screen works then it shows the board and no text. |

I didn't see it mentioned earlier, but playing Fifa Soccer (the Tec Toy release) on a US Genesis w/ Power Base Converter starts out fine, but graphically glitches out (all of the colors go dark, making it impossible to play), a couple of minutes in.
The game does work fine on my US Master System, so I don't think its a problem with the cartridge. |

US SMS Monopoly works on US Genesis + Power Base Converter for me with no problems, I played it like this for years because I did not own a Master System in those days, only Genesis + PBC. So perhaps only certain combinations of region/hardware have an issue with this game. |

PAL issue, maybe? |

Sonic 2 does work on a NTSC Master System | |

But Sonic 2 works with my Tototek flashcard on a japanese Master System using the adapter Bock made. | |

US card compatibility problem
Posted: Wed Sep 16, 2015 9:46 pm

Does anyone know which US cards work on the power base converter?
I know F-16 Fighting falcon doesn't work and i have Super Tennis and it only shows a red line in the middle of the screen for a second. I tested it on the Model 1 Genesis. i want tp know if anyone had issues with this game or any of the Sega Cards? |

Operation Wolf crashes in NTSC, but it was released in Brazil. Is it possible that version was fixed? | |
|

Wonderboy in Monster World. Similar Problem, will not work with Power Base Converter, Crashes on second screen. PAL MD and Power Base Converter. I thought my copy was faulty! | |
|

I have yet to get Space Gun to work using a controller (SMS or MD) on a MD1 + MS Converter. It works fine using the Light Phaser, but with a controller only button presses register.
Also, when reaching the demon that teleports the Beast to the castle in Shadow of the Beast all the colours gets messed up. I will try to clean the connectors, if that possibly could have something to do with it all... but other than that I do not know what could be the problem. |
|

Posted: Mon Jan 08, 2018 5:22 pm |
I think Space Gun is a Light Phaser only game. Laser Ghost is the only game that works with both control pad and light phaser I believe. (Unless you include grenade use for operation wolf). |

Though, it does say both ”Press the button” and ”Pull the trigger” on the title screen. Also, there is a crosshair on the screen which changes colour when swapping weapons... so I do think there is more to it than just being a light gun game.
This longplay shows the game being controlled by a controller: |

Sure enough you are right. Just checked mine now.
Instruction manual says to plug control pad into port 2. |
|

Posted: Mon Jan 08, 2018 10:26 pm |
Concerning Shadow of the Beast, the connectors seems quite clean. The glitching colours does however not necessarily end up the same each time playing... though. And, once they have glitched during the teleport to the castle they stay that way during the rest of the game at least up until the boss of the shmup sequence. I will give it another go tomorrow. | |

Which version of the system, USA? One of the European ones? A Brazilian one? And which national versions of these ROMS. I don't recognize these as American titles Similar questions with all of them, I currently have 2 European games, Marble Madness, (hoping the sports pad worked analoguely with the game, alas it doesn't) and Space Harrier 3D. All of the other games I own are American Systems, and I own the US Snail Maze version of the SMS.
I assume we are talking about a 3 button Genesis controller. and these are US ROMS on a US system. I need to know if I need a SMS controller modded for my fight stick.
What version of the system/ROM combos are they for? Any particular console and corresponding ROM version? And I understand is a joypad->joypad converter, not a light gun-> light gun converter. Also which Playstation light gun was it tested with, the Konami Justifier or the Namco GunCon?
Apparently I don't know whether the 3D version DOES work and the 2D version DOESN'T or if it's more random than that? Mine is European 3D and does work on a US Snail Maze SMS

Bit of a thread necro but I am wondering what the actual problem with Sonic 2 is suppose to be? The game will run at the wrong speed if started on a 50hz console that's been modded to have a 60/50hz toggle switch and then switched to 60hz. It plays perfectly fine at 60hz if the console is set to 60hz when the game starts. I have played it through now on my 50hz/60hz modded console, an NTSC SMS and a CDX and not been able to find any issues. Am I missing something or should this game be removed from the list? | |

I'm new to this forum so I'm glad for the resurrection, otherwise I wouldn't know this existed. Great top post. There should be a database somewhere that catalogs all this.
One of the games listed on incompatible with NTSC systems irked me because I've had the game awhile. I went back and tested it. Operation Wolf plays fine on my US Master System 1.3 (snail maze). There are some artifacts sometimes during shooting or getting shot when the screen flashes for a split second, but I don't know if that has to do with PAL or not. Anyway, the game is completely playable. My Japanese SMS has been stuck in customs since Feb 11, but I'm interested in verifying some of the other games with my Raphnet adapter. |

Note that in https://www.smspower.org/forums/18459 lidnariq provides a patch to fix R-Type running on the Megadrive.
I suppose we should have a section in https://www.smspower.org/Hacks to catalogue those and encourage making more patches for games not running on MD. |

With the exception of Assault City, all the other games in this list are ones that support FM, and so depend on the byte at $C000 to write back to port $3E to disable internal I/O and then read from port $F2. Without the Power Base Converter's PAL, this can accidentally disable system RAM, causing a crash. Assault City instead has dummied-out FM. See this thread: /forums/12380-VGMPackSuperBasketballFM . It retains the read from $C000 to write to port $3E, and then always just writes 0 to port $F2. (The write to port $3E is unnecessary, because it there's no bus conflict if it doesn't read port $F2) Of the games in the "incompatible with the SMS1" section, I understand the Codemasters "extra height" games, but does anyone know what's going on with the other three? |

I've tested the following games and had no problems on my USA Genesis 1 VA7 with RaphNet's Power Base Converter: - The Incredible Hulk [sha1: 235ad7d259023610d8aa59d066aaf0dba2ff8138] - Virtua Fighter Animation [sha1: ee24af11f2066dc8ffbefb72a5048a2471576229] - Wonder Boy in Monster World [sha1: da0acdb1b9e806aa67a0216a675cb02ed24abf8b] ++ This game relies on the pause button. Maybe some PBCs fail to include one. Monopoly never writes to the bankswitching registers at $FFFD or $FFFE. Some PBC don't seem to have a good enough power-on-reset signal here, and quite early on the game CALLs to $234F and then to $4FD8. I bodged in a wire from B2 ("/MRES") to SMS pin 46 ("/RESET") and now the game seems to work fine. (Note: make sure to remove any other connection. On Raphnet's converter, that's R4 and R5) For some reason, Street Fighter 2 always starts in Vs. mode; reading the manual - https://segaretro.org/index.php?title=File:Sf2_sms_br_manual.pdf&page=6 - it seems that for some reason it thinks the second player is always pressing some button? I have no idea why, because all six buttons work. 4 Pak All Action, Cosmic Spacehead, Fantastic Dizzy, and Micro Machines all use their own unique mapper, so I can't really test them on my custom hardware. For the Codemasters games, I spent a little time forcing SMS1 mode in MEKA and MESS. These games write 0 to many of the "mask" bits in VDP registers 2-6, and fixing those makes them mostly playable ... except that the sprites are displayed 32 pixels too low. It's worth re-linking to Charles MacDonald's list of known issues w/ SMS games on the Genesis in section 13 of http://www.techno-junk.org/txt/msvdp.txt |

Just would like to add, as mentioned on another post - I don't know why but
Alien 3 = wouldn't work on my cloned Mega SG converter until holding my pause button in and switching on. It technically makes no sense but now the game always works. Maybe the connectors were dirty and it was just a fluke Afterburner = doesn't work but worked FIRST try holding pause in and switching on then releasing. video coming DW about all the switching on and off from the last video, she has big juicy caps on the input and output of some upgraded LDO's, switched out the 7805's. *Sorry if i sent anyone on a bum steer - it seems that it just requires an on off on power cycle to boot. The cool thing is the region switch works so you can get the MKIII screen on bootup |

Two games in question here:
NTSC Rastan on JP Master System - Just tried this game with both converters (Raphnet and the SMS Power Adapter) and I cannot get this to even show a load screen. However, when powering on, the screen does go black and immediately flashes and then...absolutely nothing. Rescue Mission on JP Master System - Has there been any actual documentation as to why this game will not work on a JP system? Gangster Town works perfectly well for me, recognized the light gun with no problem. Rescue Mission does respond to the trigger on a JP system, but refuses to get past the difficulty screen - in other words, the gun cannot recognize the screen. Then again, Rescue Mission is notorious for being difficult to function on any system. I question if this is a problem with the JP systems or if it's just a problem with the game itself. I can barely get it to function on either of my CRTs. Would be great if someone could patch it for better compatibility one day. |

Has anyone confirmed a way to play this on a JP Master System (the one with FM sound built-in) I have the UK cart and a SMS Power gender adapter, which it doesn't work with. This is a weird situation as it was never released for SMS/MK.III in a country that officially supported FM sound, even though it has FM sound. (please correct me if i'm wrong there) Thanks! |

Has anyone experience with this setup:
PAL megadrive Powerbase sega or powerbase mini FM Cartridge version of Ghost House It doesn't seem to boot at all. |

For what it's worth, I gave it a quick go on the poor man's version of this setup, PAL Mega Drive II with an Everdrive (which I'm led to understand mimics the powerbase converter reasonably closely) and it worked ok.
It's a nice little game, if quite difficult. I'd never played it before. |
