Having a decent sf2 on miggy, even at this time and age, would be uber cool. I believe 030+AGA+4mb would be minimum (shadow fighter proved that it's possible even on an A500, but let's be more realistic) and as for the control scheme, there's always keyboard and cd32 pads (native or via the psx adapter). If the user can redefine the keys on the keyboard and the pad to fit his needs, all the better. Can't wait for the screenshots!
