I've been following the gamma loader tutorial on my wii. I successfully added the homebrew channel and all the other steps in the tutorial and ended up with the backup channel working correctly - my backup game loaded with no problems. I then repeated the proceedure on my friends wii last night. Everything seemed okay and i have done everything in the tutorial and have the backup launcher on his main menu. However i cannot launch a backup game from it. I also tried launching the backup game by running the backup launcher via the homebrew channel. This doesn't work either. When i run backup launcher the screen goes black and the drive in his wii makes a noise as if the laser keeps on moving. If i keep pressing A then the blue light comes on where the disc is inserted, then it goes off again. I have tried different options on the backup launcher configuration with no success. Eventually after pressing B+A buttons a message appears saying "reboot with hooks" and then this takes me back to the wii menu. Note: There isn't a problem with the laser/dvd drive as original games still work correctly via the disc channel. Is there something i have missed or need to do again? This has really confused me so i thought it's best to ask rather than me randomly trying different stages of the tutorial again as i don't want to screw his wii up.
