'Super Smash Brothers Brawl' Dust Issues
Apparently, due to the Wii’s design, some people may experience troubles loading Super Smash Brothers Brawl. According to Nintendo’s website, SSBB utilizes a double-layer disc which may make it more common for dust contamination to cause load errors.
Super Smash Bros. Brawl utilizes a double-layer disc which has a large memory capacity. A very small percentage of Wii consoles may have trouble consistently reading data off this large capacity disc if there is some contamination on the lens of the disc drive. Nintendo has specialized cleaning equipment that can resolve this problem. (Please do NOT attempt to clean the lens yourself, as you may damage the system.)
