Ok, so I am trying to perform the twilight hack, install the homebrew channel, use the wad manager and backup loader on my friend's wii... but she has system menu version 3.1u. I know I don't want to do a full nintendo update to the latest 3.3 and then drunkenly try and figure out how to undo the damage, so is 3.1 ok to install the homebrew listed above? I was under the impression 3.2 is needed. Please help! Do I do a full update, or can I manually update to 3.3 (but not the late-october version)? Or is none of this needed?
