In Dragon World, defeat Vegeta as Goku on Namek.
In the city, when Supreme Kai tells you about the Potara earrings, go to him to get them. When Vegeta comes, give him the other earring.

Unlock sixteen playable characters. The Adept capsule will appear in the capsule shop.
Unlock all twenty nine characters. The Advanced capsule will appear in the capsule shop.
Complete Dragon World and have all seven Dragonballs. After the credits, the Dragonballs will glow and Shenron will be summoned. The first option is "Babidi's Ship".
Super Buu's absorption technique:
Get over 10,000 Kili on Babidi's Ship
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 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: 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.
