I've said it before, and I'll say it again: fpse's near pitch-perfect PSX emulation pretty much gives high-end Amigas and Amiga-like systems a huge, huge library of games to play. Even if you throw out the really bad ones (and like all consoles, there are plenty of really bad PSX games), that'd still leave a couple thousand games to play. They aren't cutting-edge, no, but there's some great gaming pedigrees in there: Final Fantasy, Quake, Doom, etc.
What's the general system requirements ?
