pokemon ruby, sapphire and i think emerald :)
The Hoenn Region is available in the pokemon versions Ruby, Sapphire, and Emerald.
Somewhat you can insert a gb game and you can find hoenn Pokemon plus there are pleeny of diffrent Pokemon
No, sorry. (:
you can't, this game is the era before hoenn came out.
Pokemon ruby sapphire and emerald all take place in the hoenn region.
you cant get the hoenn map but if you get bthe Pokemon game Sapphire or ruby for gameboy you will be in the hoenn reigon
short answer: no
you must be talkin about Pokemon soulSilver or heartGold. no there is not a pass to go to hoenn. hoenn is not in the game. sorry -RR14
emerald ruby and sapphire
You can't get into the hoenn region in Pokemon diamond. It's a 1 region game and that region is SINNOH! BY THE WAY HAVE YOU HEARD OF POKEMON X AND Y
if you mean hoenn region, then that where the game emerald took place. You are playing IN the hoenn region.
You can't because Pokemon gold, silver and crystal, which are in johto are on gameboy colour and Pokemon ruby, sapphire and emerald, which are in hoenn are on gameboy advance. Pokemon shiny gold, which is also in johto is on gameboy advance but it isn't an official Pokemon video game.
