Things You'll Need
Instructions
Start the Mario Kart game on your Nintendo Wii, and point your Wii remote at the screen to make selections. Choose single-player mode, then choose the difficulty class; start at the 50cc set and unlock all cups needed, then repeat this for the 100 and 150cc sets. Now, choose a character, kart and either manual or automatic drive.
Note: You will have the option to choose up to four players; however, you need to be in single-player mode to unlock levels. Once unlocked you can play with multiple players in those levels.
Unlock the Star Cup by winning the Mushroom and Flower. Unlock the Special Cup by placing third or better on the Star Cup.
Unlock the Leaf Cup by winning both the Shell and Banana cups. Unlock the Lightening Cup by placing third or better in the Leaf Cup.
Repeat these unlocking steps in the 100cc and 150cc difficulty classes to unlock their cups.
Unlock the Mirror Class by reaching first place in all the cups in the 150cc class. Do this by playing all four courses in each of the eight cups. Race against the 11 drivers in these four courses and finish all of them. Score well enough between them to win first place overall. You must do this for all eight cups in order to unlock the Mirror Mode.
