No. You stay in the Sinnoh Region the whole time.
No.
You can't, the only region you can go to in Pearl, Diamond and Platinum is Sinnoh.
You never will go to a different region.
You can't, Platinum is in the Sinoh region and the Sinow region only.
You can only go to the Sinnoh region in the games Diamond, Pearl, and Platinum.
You cannot go to the Sinnoh region in Pokemon Black.
You cannot go to the Sinnoh region on Pokemon SoulSilver. You can only go between the Johto and Kanto regions. No other regions can be accessed in SoulSilver.
Just go to Pokemon platinum central and click on pokedex and it shows you where to battle all the Pokemon in sinnoh.
NO
Because Platinum the region is Sinnoh, you can't get Charmander. On Heart Gold and Soul Silver, you can go to Johto and Kanto. But no Sinnoh for Platinum.
complete the sinnoh dex and there
