I have a naomi marvel vs capcom 2 rom cartridge which has been freezing and not loading up properly. This is not the sega version with the I/O board, sound board, and powersupply. It is the capcom version of the game which is just straight jamma. I've checked the powersupply and made sure the power was in range (+5.15, +12.20, and +3.330 dc volts). I've even put the board into a dedicated naomi system cabinet but the problem still occurs. If anyone has anyone ideas about this problem and how I can solve it, much appreciated.
