How to erase data on GH3 for wii?

Question

I used a cheat code to go all the stuff unlocked in the store but now I regret it. So if anyone knows how please tell me!!

Answer 1

Wii Settings -> Data Management -> Save Data -> Delete GH3 file

Answer 2

The only way I can think of is if you go to the Options in Wii Menu, then go to Wii data, and delete it from there.
