You cannot get to the Sinnoh region in Pokémon HeartGold, you can only travel around the Johto and Kanto regions. No additional regions are available in HeartGold.
no
You cannot go to the Sinnoh region in "Pokémon HeartGold" and "Pokémon SoulSilver."
you can't get sinnoh in heartgold.
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.
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.
You can not. It is impossible for Heartgold and Soulsilver.
There is no Sinnoh to unlock in either game. If you want to access Sinnoh, you must buy Pokemon Diamond, Pearl, or Platinum Versions.
Pokemon HeartGold Will Have Sinnoh,Kanto,But Hoenn Least Likely.
you cant get to the sinnoh region in Pokemon hart gold or soul silver but you can get the starter Pokemon at slip co (i think its called) once you done all gyms and defeated red (the Pokemon with emerald version).
You dont get Arceus in HeartGold. You need to trade one from another HeartGold or SoulSilver or trade one from the Sinnoh region games. WARNIG: IF YOU HAVE AN ARCEUS ON BLACK OR WHITE YOU CAN NOT TRADE IT BACK TO THE JOHTO OR SINNOH GAMES.
Not in Heartgold/Soulsilver.
There is no sinnoh region in heartgold or soulsilver, it is only Johto and Kanto.
