today my wii decided that it was going to stop reading my zelda: twilight princess disc. normally, i would just assume that the disc was scratched and that i need to return it. however, i tried playing it on my friend's wii and it worked fine. what makes this even more confusing is that both my wii sports and rayman raving rabbids discs work normally. i keep getting the error message "the game disc could not be read. please refer to your wii operations manual for more information." what is going on??
