i understand it is impossible to play gamecube backups from a USB device because once the wii enters gamecube mode, it disables all of its wii hardware that isnt meant to be used by the gamecube (i.e. USB slots). Would it be possible to create a cMIOS that can have USB functionality? Because from what i understand about custom IOSs and custom MIOSs is that they are modified versions of the originals that have better funcionality. would this be feasable?
