I know of one, but so far it only plays self-made demos and not commercially released games.
And btw, current computers are too slow for it anyway. You need a computer with the processing power of at least 15-20x the processor of the PS2 (300 MHz) to run a game well. That means you would need a 4.5-6 GHz machine for it.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
