You cant. you can only go to johto and kanto.(if you have an arceus, you can also go to the sinjoh ruins, but that's sorta wierd and has only one purpose, plus its in northern johto anyway)
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.
no, you can only go there in emerald, sapphire, or ruby
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
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.
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.
You can't go to Hoen in soul silver.
