I earlier posted a link to tweak the laser on the gamecube, which fixes a majority of the disc read errors on the cube, but tthe link didnt get pasted right or something, and it led to a crap spam page. I am VERY sorry for this error, I feel like a retard for that.
Anyway, the cause of most of the problems with the gamecube not reading discs is not due to dirty or scratched discs, but to an incorrectly set resistance on the laser, whic is somewhat easily fixed.
This link should help.

The hardest part is getting the screws out of the bottom of the cube. I used a long skinny pair of needle nose pliers, and it worked fine.
Again, i am VERY sorry about the spam link, my forehead is bloody from banging it on the wall, and I gracefully accept any floggings coming my way for that.
