First off, the sequel to Battle Arena Toshinden, BTA 2 contains 4
extra playable fighters: 2 are bosses and the others are secret
fighters. They are Vermillion, Sho, Master and Uranus respectively.
Master and Uranus:
Press this combination very quickly as the words are coming from
the left side of the screen. The best way to do it is to restart, and
just after the screen goes blank, quickly press the combination below
(Keep trying, it takes a while to get it right):
R1, L2, WK, L1, R2, SK - You should hear a sound and the cursor
turning blue to indicate that it worked.
Vermillion and Sho:
Do the code above first, then repeat the process with this
SK, R2, L1, WK, L2, R1 -- U should also hear a sound, with the
cursor turning from blue to red this time.
Start any type of game. Goto the "?" box and hold the taunt
button to slow down the selection process. U should see their pictures
there, so enjoy!
