Crash Bandicoot 2: Cortex Strikes Back Cheats

Gold Gem
You can get the yellow gem by beating Plantfood in a certain time. The time starts after the checkpoint before the first jet ski, but it's very hard to finish the level in time. So, wait until the time runs out and then go into the bonus. Run off the edge in the bonus. When you are warped back you will have a minute and 24 seconds to finish the level and get the gem! Good luck!
