You can't. Pokemon Emerald is just like Sapphire and ruby.
Prof. Cosmo isn't in Emerald.
save prof. birch
in route 101
in my opinion emerald is way better than ruby. that is because there is battle frontier in emerald and in emerald we get a jotho starter pokemon from prof. birch after beating hoen dex!
you cant you have to pick it from prof birches choices
Prof cozmo in fallarbor town will take the meteorite he gives you a TM.
In emerald if you complete the pokedex you can get Chikorita, Cyndaquil and Totodoile from prof birch.
You get a diploma in each, in emerald you can get a johto starter from prof birch and that's it.
you took one Pokemon,may took one Pokemon and prof birch keeps the last one.
After you beat the Pokemon league in emerald you can get one of the johto starters from prof. Birch then you trade to FR or LG.
Nothing... You can talk to Prof. Birch to get a johto starter after you catch 200
