I have Mario Kart Wii and played it lots of times. I don't think you could unlock more characters. Or if you could, IDK.
there are no cheats
Unlikely. Aside from the Arcade GP series spin-offs, which feature Pac-Man and a few others, all Mario Kart games have had Mario characters exclusively, and Nintendo probably won't want to change that. After all, it is Mario Kart.
To unlock Characters in Mario Kart Wii you must beat the single player races. When you get a gold trophy in all of the races and a star ranking in all the races you will have all the characters
Get gold trophies in all cups.
