PCSX2 or something I think it's called.

I have 2 PS2 games I kept that I worked on when at Midway, now that I got a quad core pc with a nice card and too much ram I was wondering if this can run those games full speed or something?

Also if anyone here has ever bothered, is it all that hard to set up?

I kind of want a nostalgic trip with Legion and NHL Hitz 2002.
