that would be really cool. Right now im looking for a xbox to gamecube controler adapter. I really dont like the xbox but the xcontroler for the xbox really fits my hands perfect. I have a adapter for the pc and its the best pc gamepade ever. Most pc gamepads really really suck in my opinion and they are more expensive then console gamepads+adapater. so i will be post here (just cuz) all controller adapters to gamecube. more should come soon if i can find any.
doesent seem to be a stright converter from the xbox controler to the gamecube, but i wonder if i could just jack in the wii usb and pray really really hard?
sorry, couldent find one for the n64 as well, although really i never did like the n64 controler, but thats just me. But i can fully see why you would want one with the vc. stuped ps2 getting all the adapters....
