A friend added the HomeBrew channel to my wii. I don't use it, at all. I just bought the new Super Mario brothers game, but I can't update it because it says it will kill my wii if there is any non factory modifications present. What do I do? I am not a tech minded person, and I'm not very savvy with the tech lingo either. I just want to remove this thing so that I don't have to worry about it. Is there a way to re-set my wii, remove this thing, or return my wii to the un-modified factory settings?
