I have been playing the Guitar Hero games on my Wii for about 5-6 years and never had a problem before. However lately whenever I play a Guitar Hero game, while playing a song the audio will suddenly glitch out and repeat three times and then dispay a message saying "the disc could not be read, please refer to the wii operations menu for help" Guitar Hero: Metallica is the only one that works. Is there a fix??? I don't know if it is the game or the wii.
Either you should try cleaning your discs (for smudges, although if there’s any visible scratches that’s a bigger problem) or your disc reader is getting old.
Also im not quite sure but sometimes the gpu can mess with the console’s ability to read a disc. That might also be worth looking into.
