In order to do this you need both sonic adventure dx and sonic adventure 2 : battle,a link cable and a gameboy advance.
Take a chao from either sonic game and put it in the chao transporter WITHOUT a gamepak in your gameboy. When your chao is transported it will be a copy and the real one will remain in the garden you got him from. Now load up the other sonic game with your gameboy still hooked up and go to its chao garden. Go to the transporter and you will be able to get the same chao you put in the gameboy. now you have 2 of the same chao. This trick is great if you want multiple copies of the gold and silver chao from Sonic DX.
NOTE:any animal parts of your chao will return to nomal in the other gareden but hero and dark chao stay hero or dark.

Get Tails into Casinopolis early
To get Tails into Casinopolis before you beat levels one and two, you have to head to the pool near the hotel. When you enter the pool area, head to the southeast corner. Try to run into the corner and you should be stopped by an invisible wall. If you're all the way up against the wall and are facing the corner, you can fly up and head through the wall. From here, fly north, into the direction of the casino area. When you reach it, you can hit the button and enter Casinopolis!
Keep charge and still be able to spin dash
As Sonic, hold B to charge up(must have Light Speed Shoes), then while holding B, hold X to start charging to spin dash. Let go of both buttons and you will spin dash. When you break out of the dash, you will release the charge, so hold B again before you break out. This will not work if there is an enemy nearby, but it will work when near rings. After you do this trick once, your movement speed will revert to normal.

Knuckles in Twinkle Park
Yes, it is indeed possible to get Knuckles into Twinkle Park. First, grab the statue in front of the burger shop and bring it to the Twinkle Park enterance. There should be two fences, one on each side, of the door. Place the statue on the right side of the right fence. It must be put in just the right spot, so it may take multiple tries. Then run diagnally between the statue and fence. If the statue is in the right place you will slip through the door. If not try again. Once in fly toward the screen un til you see the track.

Reuse Chao Animals Glitch
In order to reuse animals, you must do this. First go to a stage and get a animal. Next, go to a chao garden and pick up the animal you want to use. Make the chao stop (Best way is with a fruit) and put the animal down about one space in between the chao. The chao will absorb the animals status and parts, but the animal will act like it was never used. Pick the animal back up and redo for quick status gain.

Tails in Emerald Coast
To get Tails in Emerald Coast (which isn't possible regularly), head over to the pool in the hotel. Quickly run to the left, and try to head towards the southeast corner. You should be stopped by an invisible wall, but if you're all the way up against the wall and in the corner, you can fly up and through the wall. Now drop down onto one of the tables that's inside the invisible wall. Here, fly through the brick wall and you should enter Emerald Coast. You can only go through the first half, since you instantly die when you reach the second half.
Tails in Final Egg
Start a new save and beat the game until you unlock Tails. As Tails, go to the pool at the hotel and go to the right when your facing the gate that stops you from going to emerald coast. In that corner, fly into the air without moving the control stick. You will fly through the roof and be able to fly out of bounds. There is a little corner of land to land on, so land on it and fly to the picture of the casino area, land there. Walk around a little bit and you will go to the casino area. Beat the casino level and that is most likly the time your going to find out that your stuck. Quit Tails story and play through Sonic's game until you unlock Gamma. Go to Gamma's game and beat his first level. Quit, go to trial mode, and select Tails. When it asks you to select a level, you will notice that there are no levels to choose from. Press A and a a box will come up and it will say the level is Final Egg, Press A again. You will be in a dark place, falling forever. If you fly around a bit, you will find a wall to go through. When you do, fly through it and you will end up in Final Egg.

Cream the Rabbit
Once you beat the Casinopolis action stage with any character, after the cutscene you should see a flying creature coming toward you. That's Cream the Rabbit from Sonic Advance, Sonic Heroes, etc. You can't do anything with Cream or talk to her, she'll just be flying by, and you can't see her again unless you beat Casinopolis again with a different character!

There are three Special Colored hidden Chao eggs found in Adventure Fields.
Shiny Silver Egg - This is found in the Mystic Ruins adventure field by going to the waterfall area. Go into the lake and look to the right. You will see a strange wall panel walk up to it and push it and the chao egg will come out from the waterfall.
Shiny Gold Egg - Go to the area where Sonic fought Chaos for the first time. Look at one of the palm tree area's and you will see an egg shaped rock pick it up. Take it to the antique store and pick up the gold egg and put the stone in its place.
Normal Onyx Egg - Go to the egg carrier prison cell. Where Amy was locked up in one of the cells there is the onyx egg step on the switch to open the cell cage to retrive the egg.
NOTE: These eggs can only be obtained once per game file

Multiplay in GameGear Games
In ANY GameGear Minigame, press Start on the Second Controller to make a second screen show up. This will allow two people to play their own game on their own screen. If the GameGear Minigame supports multiplayer, both screens will reset once a second person joins and will be synced for multiplay.
Note: This trick will work for all GameGear Minigames but if the game does not support multiplayer, they will not link to each other (In other words the gameplay will be seperate per screen).
