You go to the left and go through the portals until you get to the stage he made the speech on and go to the portal on the right and go to his room and he will be there and then you have to battle him and if and when you win he will give you a master ball which you should only use on palliative if you are playing pearl, dialga if you are playing on diamond,or garitina of you are playing on platinum. Hope this helped :)
You need a cheat on a m3 card to get a shiny Giratina
dialga bring about fifty or more pokeballs weaken it till it's hp is yellow/red but DON'T DEFEAT IT!!!!, p.s you find dialga at spear piller when you defeat Cyrus, trainer's note. you can only catch dialga on diamond. you can only catch palkia on pearl. you can catch dialga palkia/AND GARITINA!, i have platinum and caught all of then so i know post a question about how to get garitina on Pokemon DIAMOND! Actually in Diamond and Pearl u just need the Master Ball that Cyrus Gave you beforehand!
