Mini Guide if using this with a MAC Spoofer to bypass a ban
1- Make a GCT file with these codes only and in this exact order---> Mac Spoofer/Clear Profile ID (MAC Spoofer must be first code in GCT!)
2- GCT File in Codes folder of SD Card, Load MKWii with Ocarina ON
3- You will see you don't have any FCs. Go online, and join a random WW.
4- Before the course is selected, DC from the WW (If you end up searching for a WW for at least 30 full seconds, that will work too)
5- Once disconnected, go back to MKWii Main Menu and power off the Wii.
6- Delete GCT and make a new GCT file with only the MAC Changer Code
7- GCT File in Codes folder. Load MKWii with Ocarina ON. You will have new FCs, but your friend roster remains.
8- Congratz!
