I am preparing to follow the guide on correcting my system after an accidental 4.2 update (disabling my loaders and HBC). I don't have a GC controller and I don't see one at the local Walmart. Is the classic controller the same thing? Will any third party GC controller work? I don't need it for any games, just to use as described in the guides for bootmii and other hacking stuff. Do I need to look for a controller with a certain plug type? Does it need to be wired or will wireless work? I assume I can find this for less than $10, is that right? Thanks.
