Beat Dark and Hero story, then, you'll be able to select Last Story in Story Mode. Simply complete Last Stage and defeat biolizard, then sonic and shadow will turn to super, and you will face the final boss, THE FINAL HAZARD.

Get all the chaos emeralds and fight the final boss.

There are no minigames for the GBA that you can unlock in Sonic Adventure 2 Battle. You can unlock the boss battles and racing minigames, but they are played on the GC like the rest of the game.
get the 7 chaos emeralds
You have to have completed heroes story and then at the very end of the babylon's story,is the final boss,which is a ghost guardian.
You have to complete all of the special stages, then you will unlock the final boss, the time eater.
Other than through hacking, playing as Super Sonic in anything but the final boss is impossible.
the super sonic boss with sonic =.= only sonic has the super sonic boss and it has to be classic not adventure mode =.= or if classic deosint work try adventure mode i forgot witch one =.= No, I did it a different way. I did 50 man melee and got S. Sonic. S. Shadow is 100 man melee. That's just how I did it. what smash bros.
Super Sonic and Hyper Shadow were only made playable when fighting the final boss. There might be some action replay code or something for that purpose though.
