No Mariokart 2, but there is a Mariokart 7. Unfortunately, it's only for 3DS. Sir/Madam, I think this is a very good time to suggest to Nintendo to make an Mariokart 2.
There is no maniac in Mariokart Wii. Check out the characters that you can get by asking this question in the green tab: "What characters can you unlock in Mariokart?"
You have to get 15 points on every race you race in a grand pre. Its hard but it works. I have all the stars for every race! i got more characters! just practice alot! you can get up to 3 stars for every set of 4 races
A mariokart hack is when you sorta control the whole game. I would NOT do it.
It is unknown what the gender of the Mariokart character KoopaTroopa is
The next MarioKart game will be MarioKart 3DS (not final name) for the 3DS, but Nintendo hasn't announced its release date.
They allow you to get the golden wheels. U must get at least one star in ever cup on every cc including mirror.
Sadly, you cannot unlock him on the ds. he is unlockable on mariokart wii fortunately.
