How do you unlock N. Oxide? I've tried the codes but it doesn't work! Also, I've tried to go trough the shortcut that says, 'After you pass the skinny tunnel, go to the 2nd booster on the right and jump left.' It doesn't work! I am going to try it again. Can you get Fake Crash without playing the Purple Gem Cup? I've unlocked him but I accidently delete the data.
