The Atari ST version of Street Fighter II was released in 1992 and looks suspiciously like the Amiga version also released that year. Although it actually somehow looks even worse, with some of the background colors looking really bad.
I have an Atari ST but never had this game for it, but from what I've watched it plays just as badly as the Amiga version and suffers from all of the same problems: bad graphics, limited music and poor gameplay.
The Atari ST could have had a much better version than this, but U.S. Gold just did a bad job with it.
