i really dont recommend using emulator in your computer to use ps2 games... you ware out your dvd player, unless you dont mind spending another hundred bucks to buy another dvd rom....same thing with the dreamcast, you can actually play nes, snes, gen, and playstation games (ps1) in your dcast, but the fault there is that you over use the dcast and , would brake in about 4 to 5 months, i only play the nes games in the dcast because the memory in any of those games are very low........just a thought !!!
