Don't most Amiga games just use one button though ? I come from a c64 background so seriously asking..
yeah most are only single button, the most comprehensive controller would be a CD32 pad, or something fully compatible with it....
most games are single button (with up to jump, fire as fire for example, like the 64 games)
some games support one more button, like SF2, Banshee.
CD32 games may support more buttons, depending on title, but you can't use all those without an actual CD32 pad or a proper adapter for something like a Ps2 pad.
