I suggest you to try ALL the emulatorsOriginally posted by Cerberus
It looks like you were asking how to turn your PSX game into an 'emulator' (?) game.
If this is the case, then you are a little confused on exactly what emulation is. If you real PSX disk is not working with one of the PSX emu's from this site, try ePSXe. Otherwise, the game just isn't compatable.
