I recently got a Wii Fit for my Wii that's got Homebrew channel installed. When I try to run the game disc through the regular options, I am told that I need to updated my Wii and that there is a chance my Wii will be disabled if I have unauthorized modifications. I never get this update need if I try to play original Zelda/Metroid DVDs. What can I do to ensure the safety of my Wii? Is there any way for me to clean my Wii, update, then reinstall all mods?
