you can't. because the game it self (crystal,silver,gold) is a different size then the ds gba game holder BUT you can trade Pokemon from the johto region to Pokemon FireRed,leaf green, ruby, emerald, Sapphire THEN you can migrate to dimond/pearl but to do this you need 2 gameboy advance SP games.
HOPE THIS HELP :)
you cant migrate Pokemon from color games sorry
migrate them through palpark after you get the national pokedex.
Pokemon Pear [and Diamond] is located in the Sinnoh region. You will not be able to get to the Johto region unfortunately. Sorry.
To get Ho-oh in diamond, you have to have a Johto region game, trade Ho-oh to Ruby, Saphire, Emerald, Leafgreen or Firered and then migrate.
You can't get to Johto region in Pokemon Diamond/ Pearl, but you start there in Heartgold/ Soulsilver.
I don't think you can.
it is not possable
No, you can't get it, unless you play a "Johto-region" pokemon games e.g Pokemon Gold You put in the GBA cartridge on your DS and when you go to Pokemon Diamond on the main menu you will get a Migrate button click that but you should put your Bulbasaur on the PC and move to your party.
migrate the Pokemon from past game boy advanced games like emerald, firered, leafgreen, sapphire and ruby.
Sorry No you can see some of the johto league Pokemon on Pokemon diamond and pearl if you go to the battle tower. ive seen a totodile and a cynaquil already. ;)
Obtain 200 Pokemon in Pokemon ruby, sapphire or emerald, then go to professor birch and you get to choose one of the johto starters, then you migrate the starter you chose to Pokemon, diamond, pearl, or platinum.
No. Johto is not an available region in Pokemon FireRed. You can only explore the region of Kanto and the nine islands surrounding it. Currently, only Pokemon Gold, Silver and Crystal are games which explore Johto.
