Chao duplication

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.

Invincible Amy

This only works in multiplayer. The first step is to die. Then, before you are re-spawned, Hold the B-button. If you continue to hold it, you will become invincible and kill any other player you touch.

This trick only works as long as you hold the B button down. If you release it, you will lose this glitch and have to die again to regain it.
