Strange glitch in Virtua Fighter 3 I have 3 complete sets all with the same fault. 2 sets have serious problems on the video PCB but that is irrelevant. The game accepts credit but does not enter the service menu, not even through the PCB buttons. The number of rounds is infinite, the fighters'...

How do I create a compact flash for a California Speed? In MAME there are many CHD files for this game. The guides I found are for games with only 1 CHD file I tried to convert some files with chdman to img and they were not recognized in winimage

I have some racing games that are Jamma + connector for analog input. As these are games played on MAME are perfectly playable using the keyboard, I realized that converting the analog controls to fighting sticks and buttons would be interesting, thus being able to play these games on any...
