I have uses Genesis Pads with my C64 for years. They work fine with Amiga too! Also, Colecovision/Atari controllers work fine. If I could find a still working Colecovision controller, I would use it instead of the Genesis controllers... but all the ones I find at yard sales, etc are always screwed up. Come to think of, I have never had a Genesis D-Pad die on me, so I guess Colecovision controllers where less quality :-)
