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.
Use an emulator program. You can find one at emulator-zone.com.
