There exists a WHDLoad installer for Super Street Fighter 2, this one should let it play ok on your accelerated Amiga. If i remember correct, SSF2 played fine on stock Amiga's with HD, but had problems with turbo boards. I played it years ago on my vanilla A1200 with 80MB HD, was very fine. Never tried it to play again after i got a 060. I installed it with the WHDLoad installer and gave it a shot again, played very fine. :-)
And yes, i agree that this version is the best in gameplay of all, but worst in gfx, even Street Fighter 2 World Warrior had better gfx. I guess they gave up the gfx to gain more speed in gameplay. :-(
Super Street Fighter 2 Turbo has best gfx, much like the arcade version, but missing alot animation frames in the characters, no background anims and no music (not on A1200, dunno about the CD32 version). But i know why, 2MB chip mem wasn't enough to hold all gfx anims and sound in mem, so they had to give up many frames to get it to play :-(
