Yeah the snes emu sucks, but if you set the sound to mono you can play super mario world pretty well.
I just bought a DC actually, 30 bucks with 2 controllers and a VMU at EBgames. Burned all the gems, sonic 1 and 2, soul calibur, ikaruga, tennis 2k2 (and other various sports games), jet grind radio, tony hawk 1 and 2, all the goodies. Playing it constantly.
Any of you guys reccomend any other good ones?
