To get new courses, you have to unlock cups (2 in the nitro and two in the retro) by getting gold trophies in the starting cups. After you have unlocked all the cups in 150cc and gotten gold trophies in them, you can unlock Mirror (known as 'extra mode' in Mario Kart 64), which is flipped courses in 150cc mode.
Win 1st place on the courses you already have. They'll unlock the next ones.

"Nitro" is the opposite of "Retro" in Mario Kart. The term nitro refers to any cup consisting of courses new to the Mario Kart series (courses not returning from an earlier Mario Kart game).
You tell me.
i think you should get Mario kart wii! because there are a bunch of exciting courses to unlock and the characters are really fun to unlock you could also do battle on there and if you have internet connection you could play people from all over the world and make new friends!
You have to play as one player, by going to Grand Prix or Time Trials to unlock things such as new characters, vehicles, cups and courses. I hope this answer helps because this is what I do.
its Mario Kart in 3d with all new courses and there's more ways to customize your cart.
There are 8 cups total, 4 containing retro courses (N64, Mario Kart for the Gameboy Advanced, etc.) and 4 containing new courses. None of the courses is named the "Wii cup."
