How do you get all of the Baba's Crystal Balls, and how many are there?

You have to have all the characters (except Cell Jr. And Saibamen (and I didn't have Supream Kai))
Then you have to buy all their ultimate moves in Skill Shop.
THEN you can buy Baba's Crystal Ball 00
THEN! You can buy Baba's Crystal Ball 01
That's it.
(all they are is the Budokai 2 theme music w/o singing)
p.s. All of the stuff you have to buy is quite expensive so I suggest the world tournament with Sparking!!!!!!! equiped.

First you have to finish the DU with all the eleven fighters that you can use in DU, including Broly and Uub. Than, you will unlock Ultras (like Big Bang Attack) to buy. You have to buy all, and they cost 50000 each. Note that you have to have unlocked ALL the carachters that have ultras (including Bardock, and so on). When you buy all the Ultras, you will unlock Baba's Crystal Ball 00 to buy; buy it and you will unlock Baba's Crystal Ball 01 to buy (by the way, I don't remember how much they cost). There are only these two. Congratulations: now you can see two versions of the animation of Budokai2 in the "extras" section of DU, and you can buy Breakthrougs, for 75000 each :D

To get baba's crystal balls


Get every character except saibamen and cell jr
Then buy all ultimates
Then buy baba's crystal ball movie 000 and 001, and there are only 2

And the movies are useless

There are only 2 (000 and 001)

1. Unlock all Characters.

2. Purchase the "Ultimate Skill/Move" for each character at the skill shop. (30 out of the 38 have one) They cost 50,000 Zenie each. If you think that's bad,...each one has a "Power-Up"!!! Ya know, that Red "P" in the yellow circle,... Middle box of the "Skill Card". Basically, it increases the attack's strength. However, it's like buying the same thing twice.

3. After Buying all of the "Ultimate Skill/Move" from the shop (the original, not the "Power-Up"), go to the "System" section of the shop and purchase "Baba's Crystal Ball (000)"...120,000 Zenie.

4. After Buying "(000)", go back to the "System" section, and purchase "Baba's Crystal Ball (001)"..120,000 Zenie.

5. With the above four requirements met, you will now be able to purchase the "Breakthrough" capsules for all of the characters that you have unlocked: not available in Dragon Universe. They cost 75,000 Zenie each.

6. Memories of ...: As you may have already noticed (at the end of Dragon Universe, with all seven Dragonballs), you can wish for the "Memories" of a character. Just like the "Breakthrough" capsules for the
Characters NOT in the Dragon Universe, these capsules may be bought from the shop. Provided that you complete the Five Requirements listed above, the "Memories of..." capsules can be purchased for 100,000 Zenie each.
