you cant migrate Pokemon from color games sorry
It has only the sinnoh region.
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, Profersor Elm appears in the Johto region.
Pokemon Platinum is just the 3rd generation of Sinnoh, just like Pokemon Yellow, Pokemon Crystal, Pokemon Emerald and now Pokemon Platinum is just a re-playing of the series, but more things to do, rumor has it that Platinum is a multi-region game that MAY let you access the Johto Region. However it has NOT BEEN CONFIRMED yet if it can access Johto, since it is a rumor.
Bulbasaur is a starter for the Johto Region, so you cant catch him in the Sinnoh.
Cynthia is not the champion in the johto region in Pokemon heartgold,you can't find her in it, but she is the champion in Pokemon pearl,diamond, and platinum versin and that is the sinnoh region.
u don't go to johto in Pokemon platinum
There are 100 johto Pokemon in all.
no, in Pearl as well as Diamond and Platinum, you can only be in the Sinnoh region
The oldest Pokemon games to feature Johto are Gold, Silver, and Crystal. FireRed and LeafGreen partially feature Johto after you beat the Elite Four. The newest games to feature Johto are HeartGold and SoulSilver.
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 :)
migrate them through palpark after you get the national pokedex.
