Hey! I have Mario Kart Wii but I don't go online due to the number of hackers I saw on Youtube. I will give you my friend code when I start up the game another time.

Hackers usally use Action Replays from Datel (now Nintendo blocked the application with new update). They use Datel's Powersaves which it is still free today. Any hackers caught online in a Wi-Fi match will be banned by Nintendo.
Dry Bones knows everything about the Nintendo WFC for Wii and knows what Nintendo will do next and take any action.
