if you experience problem when loading brawl,don't go sending your wii to Nintendo to get repair, that a waste of time instead go to best buy or futurshop and purchase one of these http://www.memorex.com/html/products_detai...01&opento=9 (example) . These disc has small little brush clean the lens. All you have to do is put it in you wii until it say unable to read disc, then put brawl and it should work 90% of the time.
