My son just bought one (I'm not a huge fan of cheats, kind of defeats the skill purpose, but he used his own money:P), but in order to work, the wii must be running 4.3 or higher. Do I really need to upgrade, or is there an ios I can add? And if I do, what is the best way? (I know the softmod any wii is structured to downgrade to 4.1). HELP????
