Sonic Advance 3 Tips

its really easy to be honest.
FIRST-> you must have all chaos emerald and sonic as leader.
SECOND-> beat boss in final zone to get to extra zone. super sonic partner is eggman.
THIRD-> hold down R button to charge T.A. (TAG ACTION) aim at closed eye and release button.
if T.A. is at full charged, eye will stay open longer. ram it twice when that happens.
FOURTH-> when 4 arms are stretched, get ready to circle around, cause that's what the boss will do.

i guess that's all. good luck sonic fans!
