Crash Team Racing

To unlock the Nitros’ spacecraft, you must possess four Boss Keys

Immediately past the start/finish line is a channel through the rocks that allows you to cut across and miss the first left hand turn. A mask obviously makes this faster, so the snow will not slow you down.

At the first frozen lake, power slide left and jump over ravine. You will land just past tunnel bridge. A mask helps here, but is not necessary.

After making the right hand turn after the tunnel bridge, look on your left. There is a channel through the rocks that cuts across the left hand curve. With a mask, you can hit the hill on the right side of the passage and jump the guardrail to cut across.

In that battle arena press R1 on a ramp wall then you'll be able to jump up a ramp instead of going up the ramp.

While racing on Cortex Castle, shortly after the two spiders and past the flight of stairs, you will see a path that goes up into the castle. Go to the far right side and drive diagonally left, up the hill. When you get to the very peak of the hill, jump and you should land on a path that is cut off from the main raceway. This trick is hard to do but is extremely effective.
