You have to find the "red" flag as a secret goal.
SECRET
answer the secret question and your vkey will be sent to your email
after beating adventure mode a secret door with wolf in it will appear in the level "the ruins"
I think that the secret words are love, peace, and rainbow.
Check in settings, If not i dont believe you can.
Well you need to find the secret to world 8-5 so play the level once you get to the flag then jump OVER it and dunk mario a couple of times and you should find a secret.
You might be able to get the game. I don't know. Try buying Mario Kart Wii to find out. Sorry that I couldn't answer your question.
There are secret exits in levels look it up on youtube on the secret exits.
Dont know what to tell you, the secret question is meant to find your password. I guess your screwed... no offense
