Though i wouldn't bother unless you have a pretty heavy CPU. You'll need at least an AMD 64 3000 or higher to get this speed boost they're talking about.
It's a pretty damn nice development on this project though, i guess by the time multi-core processors really catch on and become the norm some 2-3 years from now, we'll all be able to enjoy perfectly playable PS2 games on our PCs.
Maybe then i'll finally be able to enjoy some Katamari action. :-)
All work and no play makes me..., well, you know the rest.
