Well, I was wrong... it is possible to dump a wii disc on your PC apparently. The only problem is that the only way to test if copies work are this 1 modchip. There is a utility out there that will allow you to dump games onto your PC. You have to have it for your DVD drive to even read the Wii disc. I haven't tried it as of yet since there is no way for me to test it.

Pictures of the wiinja install. Looks like this will be kosher for updates and online play since this connects to the DVD drive rather than the motherboard. It's on preorder in some places for $55 w/o shipping.
