I followed all the instructions about downloading the files from your computer to your SD. When I put the SD into my wii and click the SD icon Error 004 pops up and says "System Files are corrupt" What do I do??
You can't use bannerbomb on System Menu version 4.3. Also, the current HackMii Installer doesn't work on 4.3 either, so you can't install the Homebrew Channel yet. If you want to use homebrew you can use Smash Stack (Super Smash Bros. Brawl exploit) or Indiana Pwns (LEGO Indiana Jones exploit).
