Help..I have a very old slow machine running Vantage and ArcadeOS. I have verified the romset for vantuage using ClrMame Pro, so I know the roms are good. The problem is that some roms work fine (jr pacman for example), but others don't (dkong, pacman, galaga, etc). The old roms USED to work, but now something has changed and I get VMM type errors. I am running Win95. Any help would be appriciated. BTW it is running in an old converted set top box (NT-150 to be exact) and CF hard drive with no CD rom. Thanks!
