Dragon Ball Z: Budokai 3

These are located in Goku's Dragon universe. All 3 membership cards can be found on an island, just north of the Golden-Gate looking bridge. After going through Goku's Dragon Universe a few times, all 3 will be there to be collected

The cards can either be bought in the shop after you spend a certain amount there, or found in Dragon Universe by a character of high enough level. In DU, the cards appear at the same place for each character every time. For Goku, (probably the easiest character to get them with) they appear on an island just West-Northwest of the main continent. It doesn't matter how many times you go through DU, it is your character level that matters.

Beat Dragon Universe with one of the 11 characters on the Z 3 difficulty setting.

When you unlock Uub (kill Kid Buu using the Spirit Bomb) he only has to fight 3 characters to end his game (you still get credit when fighting on super hard, Z, Z2, and Z3). However, dont collect the dragonballs after the first time you beat DU otherwise you will have to fight Omega Shrenron which is nearly impossible to do in any of the Z modes.

By winning the previous levels you can unlock the next tournament levels. Inorder to do this you must purchase the capsule from the skill shop.

these are the Story Reenactments in budokai 3:

To acess a charcter's different outfits, press left on the D-pad before selecting your charcter.

Start two player or practice fighting mode with player 1 as Goku and the second player can be anybody. Then after the word "Fight!" leaves screen don't press any buttons on either controllers. Wait about 8-10 minutes and Goku should stare blankly into the screen.

With android 17 or cell use a taunt and while you are using your taunt use an energy field.If done correctly your energy field will not disappear (you won't be able to move till the end of the match).

Go to Dragon Arena, pick your Saibamen. Then fight the highest level Yamcha you can fight. If you selfdestruct on him he will automaticly die as he does in the series.

At the level select press circle and you will get the destroyed version of a stage. (Doesn't work on the levels inside buu,world tournament arena and the hyporvolic time chamber.)

To defeat the z modes easily start DU and play it till your last with very easy level. Before your last match turn your level to z and then beat the final fight and you will complete the game on z mode.

First, when you get up to Buu Saga, goto the Plains near Goku's House. After going there, fight Gohan as Majin Vegeta. After you finished fighting him, keep going through the red parts of the map until you hit up to Kid Buu. Let Kid Buu beat you, then put No in the Continue screen. After that fly a bit back, and you'll see 2 reds touching eachother. Go push X on the left one, and you can fight Buu agian, but when you win, you can fight Broly.
