I've been out of the loop since last christmas when I updated to play the new Final Fantasy. I haven't touched my Wii since and am now looking to get it up and running for sonic and Donkey Kong. What do I need to update to be current? Can I do a clean install from scratch on my Wii? My homebrew channel is upside down so I want to get it back to normal also. Its an older Wii, with a Wiikey I believe.
