Faster Sonic spins
Continuously tap X or B to spin faster.
Full pause screen
Pause game play, then press Y + X.
Get Big The Cat early
Play as Sonic in a new game and start the Windy Valley level. Go to Station Square and go outside to where the boat that leads to Egg Carrier is located. Big will be next to it. Walk up to him, press Action, and he will say "Froggy, where are you?". You will then have Big The Cat as a new character.
Play as Super Sonic
Complete the game using all six starting characters to unlock Super Sonic. Sonic will transform into Super Sonic after some time into the next game.
Play as Tails
Controller two may be used for Tails after he is obtained during game play. Note: Shields, invincibility and extra life boxes have no effect on Tails if collected.
Press X immediately before entering the snowboarding portion of the game to get a blue snowboard or B for a yellow snowboard.
Collect at least 100 emblems to get access to a special section called the Black Market on the Dreamcast Network. A Special Chao can be downloaded from this area.
Bonus NiGHTS area
Drop in the top hole while playing in the pinball section of the casino level to reach another pinball machine. Place the ball into the middle hole to fly through a warp and reach an area based on NiGHTS.
Defeating the whale
When on the whale stage(s), run over a speed ramp as soon as it appears. Then, do not press anything on the controller; the CPU will do the rest.
Defeating Chaos 6
Wait until Eggman drops his freeze bombs. Then, use the homing signal to turn his bombs into eggs and throw them into Chaos' mouth. He should freeze. When he does, attack him. Repeat this as many times as needed. When playing as Knuckles, get the Fighting Gloves then go to the trial (if you have already completed the game). If you have not completed the game, you can find the Fighting Gloves behind Big's house -- climb the wall, then go right until you find a ledge. When you fight Chaos 6, freeze him, power up, then get close to him and release the button. Repeat this two times.
Defeating Perfect Chaos
When starting, get as many rings as possible. Then, go over one of the speed tracks to gain speed. Once you are glowing blue, speed straight for Perfect Chaos and you should hit him. Repeat this as many times as possible.
Hurt Perfect Chaos at less than maximum speed
You can hurt Perfect Chaos without going top speed, although you have to be fast. Go onto the road and speed up. Stop moving during that until you are not in a Blue Shock ball, then quickly move into Chaos. If done correctly, you will hurt him without going at maximum speed.
Game Easter Eggs
Put the game disc in a PC compatible CD-ROM drive to find additional images from the game in the "extras" directory.
Sonic in the sand hill
Get on top of the ledge and pushing the button to drain the sand. Locate the sand hill cave, but do not enter. Move a short distance back out of the cave entrance. Charge up your speed of light dash, but not to the point where he says "Ready". Release, then jump immediately before you go over the little bump or lip. If done correctly, Sonic will end up in the sand hill. Note: It is just like the sand hill in trial mode.
Go to the Mystic Ruins as any character. Walk on to the platform by the train. Jump on the train and have your character face the sea. Rotate the view so that the character is facing you. It now should appear as if the character has grown to immense size on the platform.
Skip Egg Carrier loading time
There is a way to skip the loading time on the stairs on the docks at the Egg Carrier. First, go to the dock. Angle Sonic so that he is on the opposite side from the boat. Then, jump diagonally on to the stairs and keep jumping up to get to the top. For fun, jump off the stairs to see Sonic float for a bit. You still cannot get to top because of loading time, so jump diagonally onto the Egg Carrier.
Tails falls forever
In the Mystic Ruins Chao Garden, go to the far right of the garden(so that your left is towards the fence and a stone wall is to your right). Make Tails fly off the fence to the right as far as possible. The screen will turn black and you will see a blue ring trail behind him after awhile.
Tails falls through wall
In Speed Highway as Tails, fall off the path. You can fall through the walls of a building. Note: This will not keep him from falling.
