No but in Pokemon crystal you can go from johto to kanto to johto etc.!!!
You can only have Pokemon from Hoenn to Jhoto ONLY if you trade them.
sorry but you cant you can only go to jhoto and kanto which is epic so don't be greedy if you want Hoenn get emerald or ruby hope i helped
to do this i think its just like diamond/pearl so beat your rival 500 times to get to hoenn 1000 times to get to kanto and 1500 times to get to jhoto
There are Pokemon from Kanto, Jhoto, Hoenn, and Sinnoh Regions.
Sinnoh but there are some kanto jhoto and hoenn on it :)
Kanto/Hoenn-migration. Also for Johto but you must migrate from Emerald, after beating the league in Emerald, you go to the Safari Zone and there'll be a new area. In the new area you can find Johto Pokemon including the starters (the starters are EXTREMELY rare to find though.)
You can't.
Only in Emerald. Only in Emerald.
It changes depending upon which region of the world you're in (kanto, hoenn, jhoto, etc.)
If you mean the kanto region, you can't in Pokemon emerald, you are stuck in hoenn.
Hoenn is not in heartgold version, only johto and kanto are in heartgold, hoenn is in emerald
gO FIND OUT FOR YOURSELF ON www.bulbapedia.com In kanto, jhoto, hoenn, it is explosion. I don't know about sinnoh though.
