and I'll write you a superior version in Blitz Basic on an A500+ 
You probably could. The problem with the Amiga port wasn't hardware, but lack of programming talent/motivation.
The PCEngine version is one of the best out there. Yet, the PCengine uses an 8bit 65c02 (think C64, NES, atari, etc...), has only 8K of RAM!!, 64K video memory, has no hardware background parallax, 16 colors per sprite.
In my opinion the PCEngine version blows the original SNES version out of the water (both around '92) as well as the Genesis version.
The US Gold Amiga version was the first one I played and I loved it at the time though. We used to have playoffs with friends. As I remember it though, Street Fighter II was available for Amiga users before console versions (US at least). Soon after the SNES one came out we all but abandoned the Amiga version.
Still it should have been so much better and is an embarrassment when you look at the 8K version for the PCEngine (which is just so amazing).
