Crash Bandicoot 2: Cortex Strikes Back Cheats

More time in race levels
In the levels where you must race against a clock for a gem (Hang Eight and Plant Food), it is possible to get more time. With the clock running, enter the bonus area. As soon as you are there, purposely fail by jumping off the side of a platform. When you respawn in the level, the clock will have restarted with even more time than in the beginning of the race.
