you can't. Pokemon heartgold and soulsilver versions only have two regions: johto and kanto.
You can only reach Kanto and Johto.
You cannot actually go to Hoenn in SoulSilver, but you can catch Pokemon from Hoenn on Wednesdays with Hoenn Music on the radio.
use the the hoen sound (Wednesdays on your pokegear, the radio) and go to the burned tower. its found in more places but im not sure which ones.
no, you can only go there in emerald, sapphire, or ruby
You play Hoen music in certain areas. This makes some Hoen Pokemon appear.
ha ha! the person who put thi Q is stupid! don't even know!
You take your Pokemon and delete all of them except for you starter Pokemon you defeat the elite four with it only, but first catch Luigua/Ho-oh and the 2 roaming dogs and a wobbufetet.
there is.... its called Pokemon emerald, Pokemon ruby, and Pokemon sapphire.... there all in the hoen region
some of them
because the main regions are Kanto and Jhoto. Nonetheless you may get a Hoenn starter after beating the game in the Kanto region at Saffron city from Steven
Catch all the pokemon in the hoen dex. You may want to trade.
Sinnoh Sound on the radio or Safari Zone
