Sonic Adventure 2 Battle cheats
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.
