I have an USA Wii with Wiikey. Right now it´s on version 3.1 U So if I just burn Mario Kart Wii with brickblocker, will it work? Because I know that MK contains update 3.2 E Or should I just update my wii using Wi fi to (probably) 3.2U before trying to run MK? If I do this, the newer update from the internet will make my wii go ios37? thanks!
