I found some here http://www.gamefaqs.com/portable/gbadvance/code/914720.html
get the combo cards from the sonic team building in emerls story.
if your on about sonic heroes, which i think you are, then just go to story mode, and go right from team chaotics, and there should be a last story mode
There are no cheats!
If you play through the story mode you unlock every character. And if you play with another friend in a mode you can have a battle with sonic and if you win, you have him (i got him)
Continue playing through the story mode, after completing Cream's story, Shadow's will become available.
sorry but no
Yes it is true. Super sonic is in Directors Cut. All you have to do is beat every story mode 100%. Not trial mode and that stuff, just story mode.
No, but you can in the 2P Battle mode in Sonic Adventure 2 (BATTLE version only.)
you have to beat all the story modesexample:team sonic, team amy,etc
Sonic Battle is a fighting game featuring Sonic and other characters. In the virtual training mode you can practice fighting.
you finish story mode with sonic,knuckles and tails and you should see story mode Babylon and on night chase,white cave and dark desert you play jet the hawk.
Complete story mode
