i think you have to complete it and birch will give you one
you can get them by either filling all your pokedex in emerald and talk to professor birch and then migrating them or AR.
I believe Professor Elm (I think that's the right professor), anyways the one from the Jhoto region, comes in and let's you choose one of the starters from the jhoto region. Totodile, Cyndiquial, and Chikorita. Hope that helped. ~summerfirefox :3
Pokemon 152 is chikorita, unfortuntly to obtain one other then from heartgold/soulsilver, Is to beat Pokemon Emerald, all Pokemon cuaght, and then you go to prof. Birch and he'll give u the choice of the 3 jhoto starters
You can first collect all of the Pokemon for the hoen dex in Pokemon emerald you will get 1 of the 3 Pokemon gold/silver/crystle series starters then use the get all of the starters trick to get them all then migrate them to Pokemon diamond or pearl.
