So, I'm on IOS v30 (according to my bannerbomb... hope that's right). My system menu is 3.2U, which I downgraded from 3.3U in order to run backup launcher. With all these downgrades and whatnot, would it really be safe to update to 4.x (whatever the newest is, I hear you need to do it to play nsmbw). I actually am too excited over this copy of NSMBWii I've got lying here that I don't care if the update completely destroys my ability to use the HBC/Backup Launcher and any other kind of homebrew
