4.1 is the ideal system menu to be on. The latter menus were released to kill off homebrew. "If it ain't broke, don't fix it".
What should I update my wii to? Right now I'm at 4.1 and have homebrew and a bunch of other channels installed. Should I update to 4.2 or 4.3?
Stay at 4.1, and don't think of it to update. Just like wiiLike2Hacks says.
OK, thanks for the info.
