I just picked up an Epyx controller today, so far I give it a mixed review. It was OK in most games but a total failure for NES Flintstones as poor fred could not climb anything. The Jump and up don't seem to work together in that game with this controller. I could use that combo in Donkey Kong JR. I will have to pick up the NES advantage or just practice a lot to beat the Flintstone's game, sheesh is it tough!
