Use the DJ:
-----------
In order to use the DJ (that's right, the announcer!)
you have to defeat DJ in the tournament. I believe you
cannot have any "Try agains" in order to get this
character. If you're using DJ, Kenny or Tyson will
be the announcer.
Get Dual Dragoon bit beast:
---------------------------
Beat the national championship once and talk to DJ
in the lobby,and he'll give you the Dual Dragoon
bit chip.
Unlock Daichi:
--------------
In order to unlock the little guy Daichi, you have
to defeat him in Tournament Mode. When you defeat
Daichi and win the tournament (he'll randomly appear),
he will join your roster.
Unlock king:
------------
To unlock king you got to beat the game and at
the end you will see king.
