So ì would like to be able to play gamecube back ups from an external drive on my wii u, and i understand you need a gamecube controller and a device that you plug the cable into which would connect to the wii u via usb. I dont want second hand controllers or the cheap knock offs on ebay because i assume they will break easy. When i was in my local gamestore they had what looked like genuine GC controllers for the wii u, but the picture on the back of the box appears to show connecting the gamecube cable directly into a wiimote. My question is will that still work with homebrew GC backups, or would it only be useful for wii/wii u games that support GC controllers. Thanks
