First you have to beat the GT Saga in story mode, then he'll randomly be summoned when you gather the Dragon Balls.
What you do is once you have the Dragon Balls, save your game. Then summon the Dragon, and if you don't get the one you want, wish for stuff anyway but don't save. When you get back to the main menu, load your save game and try again
Which dragon shows up is completely random. But if you want to make sure you get the one you want, save right before you summon the dragon. If green shenron or porunga come out just reset your PS2 and summon the dragon again. Keep doing this until you get the one you want.

You go into goku's 2nd or 3rd du before your last battle with buu don't go to it instead fly around it and when you get to a ??? it will be supreme Kai and he tells you that he senses a stronger power level than majin buu's and then go to the red dot it will be broly defeat him then goku will find a paper falling from the sky then go to the red dot and you should have to fight uub then you should go to the last red dot fight omega shenron and unlock him
you cant trust me I've have beating all of the dbz games and the highest is ssj4 but on dbz ultimate tenkaichi you can go ssj5
use the dragonballs and hope its the red shenron if its not hit the reset button and try again
Goku and Vegeta
Heh I remember how I had trouble with this. You have to hold x and at the same time double tap left on the D-pad and hold that.
you have to kill grandpa gohan in destined rivals
Not yet but keep an eye out for it because they did put AVGN and Legend of Neil on DVD....considering how popular DBZ Abridged is and that they are on season 3 now I'm sure it will happen soon enough
Probably not because of the bad reviews it got. But I wish there would be. Yes there will be a alpha and omega 2 lions gate has comfirmed it. Tt will probaly be coming out in 2013
