Have had a wiikey fitted into my sister Wii for the last 3 year and has been working flawlessly. But recently my sister told me that no games would load throught the disc change kept coming up with disc read error, i though no problem probably just need updating using pimp my wii program. Now the Wii is up to date with latest CFW and all cisos aswell. The Wii will only read retail disc but now backup disc, is there a software error that would cause such a fault or do you think the Wiikey is screwed??
