Couple of final questions before I continue with Chapter 2 for my 4.3U boot2 Wii modded with SmashStack, this WILL downgrade it 4.1U so I can play burnt discs, correct? I WILL be able to access the Internet Channel/Wii Shop and play all the games I can right now online right? (Mainly Modern Warfare 3, as I know it's required to be on 4.3U to play online) If that won't work, can I skip downgrading to 4.1? The only thing I'd be missing out on is the ability to play burnt discs, correct?
EDIT: Before I use MMM I'll need to put the ModPack NTSC-U, CIOS-PACK, and IOS Update on the SD Card, correct? Or just ModPack and CIOS-Pack?
