Kengo: Master of Bushido Game Cheats

Be Student:
Go to the character select screen and Hold L2 + L1 + R2 + R1 while you pick your character. This only works in 2 player mode.

Confuse the enemy:
If you keep pressing X and O at the same time it will confuse your enemy even if your attacking or not (only works on "versus" and possibly "tournament).
