Anyone have problems with the A or B button on the official gamecube controller? What happens to me is, after some use the a or b or both buttons feel dead, they won't push down or pop up. I heard of a fix of twisting the controller and that does help, put only for a round or so of smash brothers and then I have to twist again. I bought 2 extra controllers and the one that comes with the system all 3 have had problems and I've exchanged one that was real bad where the twist trick didn't work. Before I take one apart, has anyone else discovered a fix?
