i heard of a guy that moded his and it and it did an auto download on the nintendo site and burn his console. pretty much a brick. But there are home Brew apps that you can run and emulate games though
I'm about to mod my sisters wii, and i know a guy thats been doing this for about almost 2 years now. let me know if you are interested. I can give you his number, i think he charges a bill or so, but i can be wrong, haven't spoken to him a while.
