Hi guys, In anticipation of the release of Skyward Sword, will I be required to have my Wii on system menu 4.3U? I'm on 4.2 right now. Will I have to ModMii this thing again? What will I need to do? I don't want to screw this up. In all honesty, I'm confused, as my latest cIOS was like rev 19, and now I'm seeing this rev 21 d2x thing and I'm like what is this...?
