This is technically able to block your wii, but will most likely result in you not being able to play GameCube games, but this can be solved in the future when a GameCube Mios fixer/restorer is released.
The rungcbackup.dol copies the gcbackup launcher to memory and changes to GameCube mode and also patches the DVD read functions in memory, to make reading DVR-r's in Gamecube mode possible. While in the Gamecube mode it is almost impossible to access most of the normal Wii functions, and most importantly, it is almost impossible to access any homebrew application. How it works: The Wii has two modes a wii mode that lets you play wii games and a GameCube mode that restricts the access of the wii to its wii systems and lets you play GameCube games. Ever wish you could play those GameCube backups on your Wii? Well with my help you can.
