Super Buu's absorption technique:

Control opening screen:
Rotate the Right Analog-stick to spin Master Roshi. Press the Left
Analog-stick to change his position on the screen.

Hint: Easy transformation:
Instead of having to press the P + K + G, press R1 + R2 to
transform. This works with all characters who transform in any way.
This can be very useful if you want to knock the guard off your
opponent while standing next to them.

Hint: Easy capsules:
Select the skill shop, press X, and when Bulma says welcome hold R1
+ L1 + L2 then press Triangle(2). Then, go back and do it
repeatedly. Every time you do this, you will gain new capsules. Keep
doing this until you reach 100%. The last few (98-100%) will take
some time, but you will eventually get all the capsules,
breakthroughs, characters, stages, skills, etc.

Hint: Easy wins:
Get a Viral Heart Disease Skill and put it on for support. Then, get
a Vaccine to not make your Power decrease, but your opponent's will.
Just block until their health is in the orange. You should now be
able to defeat them.

Hint: All characters:
Successfully complete novice and adept modes in tournament and save
the game to a memory card. Get a different memory card with no file
from the game. Complete story mode and go to Mr. Popo's shop. Put
the memory cards in slots one and two. Trade the Dragon Ball from
the new saved file on memory card two to Memory Card one. Remove
both memory cards. Put the memory card that was in slot two into
slot one. You will now have all the characters from the saved game
file on memory card one.

Hint: Yamcha: Easy unlocks:
Play Stage 3 of Babidi's Spaceship with Yamcha only using Wolf Fang
Fist to unlock Dabura, Majin, Super and Kid Buu along with some of
their moves much faster than if someone else was used.

Hint: Defeating Kid Buu:
Play as Goten or Kid Trunks. Have them be Super Saiyan and have two
capsules of Kamehameha or Buster Cannon. Also get a quick fire type
move such as Continuous Kamehameha (if Trunks has one). This works
well because if you are tall (like Goku), you will kick over Buu's
head.
