Did SNK make Mahjong games prior to the Neo Geo?

Update on my problem. I officially have no clue what’s wrong with the board. I have no replaced every capacitor, tried new eeproms for all slots. Reflowed all connector points. Replaced U5 and U6. Also replaced U20 as it looked like the pins have corroded. However no dice and I still have the...

This worked mostly, only crossed swords 2 has the sound issue still

PMed about samurai shodown 6

Yeah i can do that, Ill do it and report if it works.

I replaced the MVS board and lowered the voltage to around 4.9V. I still get the issue occasionally of the sound cutting out, although its not as frequent as with the other motherboard. Should I continue to lower the voltage?

Its a namco cyberlead with with a nano ms-9

I recently got an RGB pi jamma and I've had issues with the video. It works fine on my supergun but on my candy cab the video is all scrambled and seems like its a bad sync signal. It has video ground connected so I am not sure what the issue could be? Does anyone have any ideas on what the...

Bios didn’t change anything. I am potentially thinking maybe this is a motherboard problem not a cart problem as now I get no sound at all and even in bios testing the sound doesn’t play. There are also some missing components on the bottom of the board that could be suspect

When I lower it to 4.9V it works mostly but still has random cutoffs where the sound stops. When I put it at 4.8V I don't get any sound stopping but I get visual artifacts and it randomly resets. Any ideas on a fix?

I had it dialed in to exactly 5V and it still randomly cut out. Whenever it cuts out often sound effects will still play just not the main track. If I try to force it to play a main track through the unibios it wont do it.

I recently got my multi mvs and am running it with a mv1fs. I am having issues with the sound however where sometimes random sound effects play, its playing fine then the sound cuts out randomly or fades out when its not supposed to and plays random noises. I am getting 5.3V and 12.3V on each...

I recently have tried to get a pandoras box on ali express but everyone I get even when advertised as crt compatible does not output 15khz. So I am looking here for a 15kHz compatible pandoras box or similar item. Thanks

I recently got a new candy cabinet so bought a cheap mvs board on Ali express with a 161 -1 to put in it. Today I was letting it run however it randomly started having graphical glitches. Reseated the cartridge but issues remain and are in photos attached. I don’t have another cart to test...
