Dragon Ball Z: Shin Budokai - Another Road Cheats

Hold L and press X when selecting a character's Super Saiyan form. A sound will confirm correct code entry.

Go throughout story mode (Another Road) to unlock the following characters:

Beat arcade mode once with anybody and then go to the options menu and select bonus, and you can listen to in-game music and play "dragon click".

Select Goku on normal mode on the charcter selecting. Then hold L and press circle. Then you will hear a click sound. Then it will show super saiyan 4 of Goku.

To start in Super Saiyan form when you immediately start a battle, hold R when choosing your character and press X, and you'll hear a "cling" sound, different from normally choosing your character with no R held down. Remember, for this to work, you have to hold down R and press X on the Super Saiyan form when choosing, not the normal one.
