All Working Kengo: Master of Bushido Cheats - Playstation 2

Play as a student
Hold [R1] + [R2] + [L1] + [L2] when selecting a character. Different characters will result in different Dojos and students.

All hidden characters
To unlock all the hidden characters in Versus and Tournament mode, defeat all the Dojos in single player mode. All the silhouettes will be replaced by the faces of the Dojo Masters.

Confuse opponent
Repeatedly press [X] + [Circle] during versus mode to make it unclear whether you are going to attack.

Dojo stage
Hold [Select] when selecting the random stage option in versus mode.

More difficult illusion training
If you choose the illusion training and complete it enough times, you will have to fight a "mirror image" of yourself. This "mirror image" uses the same weapon, and can use any attack that you have. It is an easy battle but it can definitely show you weaknesses in your own technique.

Fight with a plank of wood
Get your sword up (extremely), and go to training. Select the training where you beat up on a piece of wood and attack it. Note: This trick works if you hit the wood only once and it breaks.
