I had a 3.4 firmware Wii but updated it to 4.2U because I couldn't get into DLC in RB2. ( I updated via the system menu )
Now it's not loading my RB2 backup.. My other backups work (Super Paper Mario, etc..)
Can anyone shed some light on why this is happening?
Oh yeah. I installed Homebrew and a couple of wads (for the dlc) before updating my system.
