It is not possible to change the in-game region on Pokemon Emerald. Each Pokemon game is coded to be set in only one region. This means only data for the Hoenn region exists in Pokemon Emerald. Pokemon Gold, Silver, Crystal, HeartGold and SoulSilver are the exceptions as they are set in Johto and Kanto.

Advance map works for any Pokemon game on Gameboy Advance. In it you can edit maps, change maps, make warps, change sprites, write scripts, events, etc. If you're looking for a place to download it you should type in "Advance Map Download" in google. If you can't find it then look at some tutorials on youtube because sometimes they provide you with a link. I could find you the link myself but I'm about to eat lunch. LOL
