I found my brother's old Wii today and to my surprise, it's still on 2.0. I want to homebrew it, but I don't want to risk updating to 4.2 with Ninty's shitty code. I don't have Twilight Princess, so what would be the best way to get Homebrew it to use some sort of safe updater to a higher firmware? Will Bannerbomb work on 2.0U?
