Well, the problem with Amiga beat-em-up's it that they just never delivered the complete package. Some had excellent graphics (Capital Punishment, Elfmania, SSF2) but lacked in gameplay or sound department while others played like a dream (Body Blows, Shadow Fighter) but lacked visual polish. IMO Fightin Spirit delivers in all departments though it is starting to show its age, too.
A while ago I was playing some old SNK beatemups using NeoMAME, those games are still worth playing.
