I know that they ban Wii using the MAC addresses and since there was this Ocarina code that was recently released to bypass this ban, I'm just wondering how does it work? I know that the code allows users to change the last 2 digits of their MAC address to any other 2 digit combinations to bypass the ban but I want to know why it doesn't work for USB loaders and if I'm banned from one game, does that mean that I'm banned from my other WiFi games? Also, is there a way to permanently change your MAC address?
