hi folks, I just ordered a third party classic controller with gamecube port: Warning: Spoilers inside! and to my surprise, it is quite compatible with Wii homebrews. no crashings so far, I have tested it with console emulators, usb loader gx, and nintedont. the catch is, you cannot use it as a controller on pc using the third party wii u/pc gamecube adapter. I don't know why. also the cable is very short, you may want to buy an extension cable. if you are looking for for a cheap gamecube gamepads (without the ability to use on pc), I definitely can recommend this. the price is about 10.80 dollars.
