On the title screen, press RIGHT. The first time you do this the word "Rules" will appear, followed by verbal instructions for the game. After the instructions are over, keep on pressing RIGHT until you get back to the start screen.

Press RIGHT one more time and it will paint the same smear but in a different color and it will say "Basic Technique". Then it will give you the basic techniques verbally.

In Wars mode, as soon as your life meter runs out press the TRIANGLE button and the characters that are left will speed up their progress in the round.

NOTE: This works ONLY when nothing but computer players are left in the round.
