I had a crack and succeeded at unlocking my Wii character for Mario Kart Woohoo!
And so I now I can play online as Mii.
How to do this:
- 1. You need to play off line in single player mode.
- 2. Win all the cups (by coming in 1st, 2nd, 3rd) until you unlock the ‘Star cup’
- 3. Win the Star cup to unlock the ‘Special cup’
- 4. By winning the ‘Special cup’ you will unlock your mii
So what are you waiting for? Get your mii ass on the grid.
