some of the codes are hard and have to many key words. If you typed it correctly then it might work this time.
I know you can get Omega, i heard that he's playable in the game using his password from Budokai 3.
ya but people also heard you can unlock sonic and tails in ssbm!
Not to go off topic but, I hated that tails and sonic rumor, when I was in the 3rd grade, me and my friend saw that in a magazine and we spent like a bazzilion hours trying to get them.
But anyways, I heared that you can't get any of the characters that aren't in DBZ Budokai tenkaichi already.
