Forgive me if this has been answered elsewhere, but I've noticed that the last 6 months or so, pretty much newer game every disc I've put into my Wii has told me that a system update was required to run it. Not sure why, since I have 4.3 already. I can get around it by just installing the game to a USB loader or running through Gecko... But I'm curious what it would do if I told it to go ahead and run the update? Would it just reinstall 4.3, and clear out any homebrew I've installed?
