You cannot go to the Sinnoh region in "Pokémon HeartGold" and "Pokémon SoulSilver."
You cannot do anything in Sinnoh in HeartGold. You can only go to Johto and Kanto. Sinnoh is not available to travel to.
you can't get sinnoh in heartgold.
No but you can go to kanto but you can own sinnoh pokemon.you cant
Pokemon HeartGold Will Have Sinnoh,Kanto,But Hoenn Least Likely.
I think your talking about HeartGold/SoulSilver. In Pokemon HeartGold/SoulSilver you're not capable of going to the Sinnoh region, only Jhoto and Kanto are avaliable.
no that is a separate event
Just Johto and Kanto.
