Please forgive me if this topic is all over the place, but I did a search and everything and can't seem to find the answer! How do you use your own Mii character in place of a Mario Kart Wii character? Do you need to beat certain levels ect...? So sorry!
u have to win 100cc special cup for outfit A, for outfit B u need to play 4950 races i think or unlock all the expert ghosts in time trial, u could have looked in the mario kart wii info thread
