I've played it on MAME on a keyboard a long time ago... I had some time to kill at school, and I downloaded MAME and a couple roms to their PC and tried it out - wasn't that bad, but some limitation on the keyboard only registered two keys being pressed at the same time, which made a dragon punch/yoga flame damn near impossible - forget about even thinking you can perform any of Zangief's moves on that setup. 'course, that was back with SFII, before all this "Alpha/Zero" shit, and the countless sequels/spinoffs/emulation progress we have nowadays. Hell, judging by some of the recent activity here, that was probably before most of the forum posters even knew what an arcade game was. Long live the real thing, baby.
