I know how one can just download a ROM and play them on an emulator or even your handheld console these days but, why go to all that trouble when you can just visit a webpage?

Metaboli has set up a Flash version of Capcom's older "Street Fighter II Championship Edition" released back in 1992 to help promote the latest title in the series, "Street Fighter IV" and it plays pretty well. Just kind of hard to pull off special moves with the keyboard...

If you still haven't got SFIV yet then, maybe you'll want to test out the benchmark program to see how well it would run on your PC.
