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 go to the safari zone after you finish the game then, if you see a new path go to the grass and you can catch Pokemon from the jhoto region
