Hint: Wang Tang's "Agile Dragon":
Start an arcade mode game and select Wang Tang and use the default controller settings. Collect all Power Stones and hold L. The Dragon Ball will eventually grow to twice its size after approximately ten seconds. .Note: This trick will not work on "Gunrock's" level and is best done on levels with low ceilings and large open spaces.

Hint: Get on the roof:
When in the Mutsu board or against Ryoma, sometimes the stones will go on the roof. To get on the roof, you have to climb on the ceiling and go towards the edge. If done correctly, you will be on the roof. Note: When this is done, Ryoma will follow you and time will run out. You will also not be able to get any items.

Hint: Sesame Street reference:
On the Londo (Falcon's) stage, at the top left hand corner there is a window containing a very familiar Sesame Street character. As you are fighting, Elmo will be watching with a big smile on his little red face.

Hint: Devil Sickle:
A sickle that you swing to hit someone. It is not too painful of a weapon, but you can get people trapped and hit them repeatedly.

Hint: Ice Sword:
This sword freezes anyone that you hit into an ice cube.

Hint: Lance Of Lava:
This is probably among the cheapest weapons in the game. Attacking with it will cause fire to rain from the sky on your opponent. This can be used three times before the lance runs out.

Hint: Morning Star:
This is perhaps one of the best weapons. Your character swings the morning star around, and if anyone is near when you swing it, it will hurt quite a lot.

Thunder Sword:
The thunder sword electrifies your enemies.
