This will reset all of your stats to the base number they would be at the level you are at. Except it will reset your materials and you will loose all of your items. The only thing you will keep is your level. This will also come in handy for when you max your stats but wish you hadn't. That is all I would suggest using it for. Get your character ready to go online that you wanna reset materials with, but at the bursting screen to load online put the 1st memory card in slot 2 and the slot 2 one in slot 1. If you only have one memory card just remove it. When it finishes loading it will give you the disconnect error. Dont hit start just turn the gamecube off. Load up your character to go online. When online loads it will tell you that there was an error and that c-mode and items will be reset. Yippee! your done! have fun kids!
