you don't do that you have a Pokemon game (emerald,Sapphire,ruby,etc.) and one option is migrate Pokemon from so called game
What?!?
You can remove a capsule from a Pokemon by visiting a building with a PC, using the PC and choosing "Your Name's" PC. You should then be able to edit, move and remove ball capsules.
you need to steel a flag
steal other players flags, when you get enough you can remove boulders
you are able to remove all boulders. I say its worth it
Once you obtain a badge it's permanently stored in the badge case.
50 flags stolen=platinum(remove all rocks in base) 10 flags stolen=gold(remove 10 rocks in base) 3 flags stolen=silver(remove 5 rocks in base) 1 flag stolen=bronze(remove 1 rock in base)
When I found him he was in Sky Stiarway 7F. He could remove but he is in Sky Stiaway. You don't need a Secret Slab or a Mystery Part.
It may be hard to explain but its easy to do. When you start the game, be sure you have an emerald, sapphire, ruby, leafgreen or firered game pack in the lower bottom half of your ds. When you start the game diamond pearl or platinum, you have choices before entering the game. There is migrate from [e.g: Pokemon emerald] Click this and you will be able to transfer 6 Pokemon from that other game [gamepack] you can only migrate Pokemon which do not have hidden machine moves [e.g: surf] So go to the guy next to the big store in lilycove city and he can remove those moves. I hope this helped.
I have Pokemon pearl but it worked for me and it should be the same. Go to any Pokemon centre and go to the PC. It'll then ask you 'Which PC should be accessed?', click on your own PC, then ball capsules. Click the ball capsule that your Pokemon is attached to then click Remove. Hope it helps :)
In the Pokemon Center, at the end of the desk. Then select the top choice. From there you can do various things, like deposit Pokemon, withdraw them, move items between Pokemon or remove items and put them back in your bag.
Well, the Griseous Orb transforms Giratina into it's other forme in Platinum so, you can't actually get a Griseous Orb in Diamond. But if you trade Pokemon with someone who has platinum (and Giratina origin form) you can remove their griseous orb and give it to your giratina, it may change forms.
