Can you tell me the games that fail to play back? I can fix them.
A lot of the systems are pretty solid though, it's usually the more obscure things that need a fix.
For example, these systems are capable of recording a game from beginning to end without an issue:
NeoGeo, PGM, CPS1,2, NES, SMS, Kaneko Suprnova (cyvern), Cave cv-1000, Sega System 32, Sega C2
if you have trouble with any of those, be sure to check out the recording tips link here:
