Crash Nitro Kart

If you get a boost weapon, keep it. About halfway through the track you will see a corner with a bit missing off the fence. Use the boost weapon and drive through the window. Use this if you want to cut that corner. Also, Aka Aka, Uka Uka, or Emperor Velo will work.

Get past the gears that splatter you if you get too close. When you go in the clock tower, do not turn left. Instead, go straight, jump on the gear, then follow the rest of the gears. This helps when you are trying to defeat N. Tropy's ghost.

During this track you will reach three boosts in a row. On the third boost, jump to the right. You should land on a platform. Use this if you want to cut that corner.

Finish in first place in all sixteen races in adventure mode. This includes the four Boss races as well as the twelve normal races. You will then be challenged by Velo to a race on the Hyper Spaceway track, which will now become unlocked in the other modes.

After the boosts with the fire part, you will go through a warp and exit in a mountainous region. After a few jumps, move to the left side of the ledge. Before the last jump, turn sharply to the right. You will drive off a ramp that will take you to the next part. Be sure to use jump boosts or you will not make it.

To get the CNK token letter that you see in the air during this race, after you have gone over the first bridge, find an opening between the end of the bridge and the wall. Drive into the water closest to the wall and you should end up on top.

About halfway through the track you will see a piece of hanging track on the left. Go directly next to it and hold R. Make sure your car goes on the track. This is useful in time trial mode, as there are a few boxes up there.

During the race you will see a track with a fence in the air. Use the hill to jump on it. There is a CNK token letter up there.

Jump over the fence with the arrow over it.
