Clockwork Wumpa: Shortcut:
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.

Deep Sea Driving: Shortcut:
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.

Hyper Spaceway: Shortcut:
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. 

Inferno Island: Token Letter:
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. Do not 
use this as a fast cheat because it takes a while for Aka Aka (or Uka Uka and 
Emperor Velo) to get you up there.

Jungle Boogie: Token Letter:
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.

Jungle Boogie: Shortcut:
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.

Finding Shortcuts:
To find a shortcut, look for a large red arrow with a yellow outline. Most of these 
arrows let you go through them (under), the opposite direction, or around them. 
Be careful, as sometimes when you notice them too late there is not enough time 
to find or get the shortcut.

Play As Emperor Velo:
Complete the game 100% as Team Cortex in adventure mode. You may need to 
play previously as Team Bandicoot. 

Android Alley: Shortcut:
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.
