you can start as many times as you wants, the private folder includes installed games and some data, you can simply use any SD card [2gb or less] and sometimes higher, and start the guide, the private folder is not neede,d if you dont have anything on the wii that is primordial, then just format it as fat32 and start the guide.One 'dumb' question. Am I safe in just doing a fresh format in FAT32 and wiping the 'private' folder or should I copy that to a temp folder and replace it after formatting to FAT32. Card is currently FAT so I need to format regardless. Thanks in advance.
