At the title screen, press Up, Up, Down, Down, Left, Right, Left, Right, Sguare. It also shows the code on page 9 of the instruction manual.

On the levels where Crash rides the motorcycle, it's easier to beat the time trial if you wait about a minute before starting so that the other vehicles don't knock you off the road.  Then, you can hit the clock and still proceed normally.

To get to the Bonus Levels you must aquire 5 relics, which you get by beating the time trails. For each level you must have a certain number of relics to enter (increments of 5).

When you are playing a level that has the rock throwing monkeys, after you have destroyed the vases that they occupy you can jump on the cowarding monkeys and get free apples. 

When you reach the dead end with the picture of the light purple gem in a square border, keep on super bdoy slamming (X and O or R1 buttons) to break hidden boxes.

Here's a tip, before you try to beat the levels in Time Trial, wait until you beat Cortex the first time, the super power he gives you is "Crash Dash" which enables you to run faster which will help you get Gold Relics instead of Sapphire ones in the time trials

Green Gem Level 23 Flaming Passion:
Take the hard path.

Blue Gem Level 20 Tomb Wader:
Take the hard path.

Yellow gem Level 7 Hang'em High:
It shows the yellow gm on this level but you must actually get the secret warp zone and go into level 27 to aquire it.

Red Gem Level 12 Deep Trouble:
To get the red gem you must go to the end of the level and then you must hit the ! box at the end. Once you have done this go back down the tube and to the right tap the TNT box to set it off and then go through to get the red gem.

Purple Gem Level 13 Hang High:
Get the hard path and take it.

In level 9 Tomb Time, there is a way to access the Purple Gem path without having the Purple Gem! Towards the end of the level, the last creature you kill is the snake. After you kill the snake, turn left, and you can see a platform. Instead of going ahead, hitting the exclamation point and finishing the level, do a slide jump to that platform. If you jump perfectly you'll land. Do another one to the next platform. (HINT : It's a lot easier to do when you get the Double Jump power by defeating the 2nd boss, Dingo Dile. Then you can do a Double Slide Jump, and it's easy) But once you do the two slide jumps, you're at the end of the Purple Gem path! On the path there is a clear gem you can grab. And to get the gem for smashing all of the boxes, go through the Purple Gem path backwards, smash all of the boxes, then come back around the regular path, and grab a second clear gem at the end of the level!

In the levels GEE WIZ and TOAD VILLAGE there are several fun things to do with N.Gin's bazooka. Go up to that annoying chicken, aim, and fire! Now wasn't that nice? Next, go to a wizard. Don't go within range of his spells, though - aim, fire, and when you blast him his clothes and beard fall off! Don't worry, he's still wearing boxers. Blast him again to kill him from long range.

Walk backwards as soon as you start htis level. There will be 4 boxes and one of them has an extra life.

When the second red light lights up on any of the motorcycle levels. Press and hold X and you should do a wheelie. This will allow you to start off faster.

In level #16, "Sphynxinator", when you start the level go backwards until you see boxes. They will contain 12 wumpas and 1 extra life!

When you go to the end of the yellow gem path, jump over the gem and keep going. You will come to a steel block wall. Slidejump, then do a double jump over the wall and you will see 5 lives.

The level Hot Coco can be accessesed through Road Crash.  When you see the sign that shows an alien head, hit it and you will be transported to Hot Coco.

Start level 11 and get onto the gold gem, and then go until you start racing. Get caught by the second pterodactyl to go to the secret dinosaur level.

When playing, go to level 11- Dino Might, and go into the gold gem path. Follow the path until you get to the ptridactyles. Pass the first one, and when you get to the second one, jump into it and you will be transported to a level where you ride the dinosaur through the entire level.

If you have the yellow gem already, do a double jump over the yellow gem at the end of the path. Here you will see some steel boxes stacked on top of each other. To get 5 extra lives, hold Circle and press X to jump. At the top of this jump, press X again to do a triple jump. Do this to get over the boxes and get 5 extra lives.

Beat 100% of the game. After you defeat Cortex you will get the new ending.

• Tiny –- When Tiny dispatches the lions stay near the bottom of the screen to avoid them. Afterwards, dodge his trident attack and when it gets stuck in the ground counter with a spin-attack. Three spin-attacks defeat Tiny.
  
• Dingodile -– To beat Dingodile, stand back and avoid his laser attacks. As the frequency of his attacks begins to dwindle, run in spin-attack him and run out. Dingodile is defeated by three spin-attacks.
• Dr. N Tropy -– To defeat N Trophy, avoid his heat-seeking missiles and gun blasts. As he begins to tire, construct a staircase to his platform, run over and spin-attack him before running back. Three spin-attacks are enough to defeat Dr. N Tropy.
• N Gin -- ???
• N Cortex -– To defeat the final boss, Neo Cortex avoid the heat-seeking missiles and exploding mines that he tosses at you. After they explode, knock him into the sewer. Neo Cortex is defeated after three attacks. (Note: In the final showdown, Crash battles N Cortex while his friend, Aku Aku fights Uka Uka, Cortex's boss. Be careful and stay out of their way. The firepower from either side will kill you. Additionally, when Neo is knocked into the sewer, Uka Uka becomes more difficult for Aku Aku to defeat.)

from (tylerdid@worldnet.att.net) In the "Road Crash" level there is a sign. It is on the left hand path and has a picture of an alien on it. If you run it over, you will reach level 31,a secret level

When racing against the UFO's, you fall down holes. Just follow the wumpa fruit and it'll take you around the holes.

You must defeat Cortex with 44 gems and 30 Sapphire or better relics.
