PCSX2 and it also requires the PS2 Bios
The PlayStation (or Playstation2, or PlayStation 3) simply does not have enough processing power to emulate most Windows games in real-time. If you have the PS2 Linux kit or a fat PS3, you can install Linux, and then run Windows inside an emulator called QEMU. This will be extremely slow and probably unusable for most games beyond Solitaire.
