Please note that Bannerbomb does not work for everyone at this time.
If your Wii freezes while trying to use Bannerbomb, follow these diagnostics:* Make sure you're not trying to use the SD Menu on System Menu 4.0 (the little blue SD card button in the lower left).* Check that you pressed the Channels button in Data Management.* Try a different version of Bannerbomb. Most people should be able to use aad1f, but some might need another version.
