Well I think as far as I can recall its retro cup!!!
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.
To unlock nitro ball in super stick golf. Reach 30 achievements to unlock.
"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).
There is no code in crash nitro kart at all because i have even searched for a code to unlock everything in the game so yea.
