fighting spirit and shadow fighter are both excellent. For some reason I keep getting a "not enough memory" error from fighting spirit though, despite 64 megs of RAM.
It ran on my old 8 meg card so who knows.
Back in hte day, we played both Mortal Kombat (2 especially) and Street Fighter 2 a fair bit on the amiga. Nobody had a console anyways, so never bothered us that there were better versions
