I plan on updating to 4.0 (so I can play madworld, and save channels to my SD), but not through nintendo, so I can keep my homebrew. I also install .wads, so I dont want to lose that either. I am currently running 3.3u, and the last cios I installed was the one required to play onslaught for wiiware. What method of updating to I need to do? Do I need to update to 4.0 to play madworld, or is 4.0 just for the save to sd? What are my options?
