Complete some sort of sidequest in LG (defeat team rocket in Island 5) and you get that ability to trade with RSE.
there is no national dex in Pokemon emerald. but, you can trade it from Pokemon leafgreen, and firered.
you can get the national dex from prof. birch after deafting the the elite four. then you can trade larvitar from leafgreen or firered. you can find larvitar in the seventh island in leafgreen/firered
You have to fix the network machine in leaf green and get the national dex in emerald
Yes but only by using wirless adapters and only after receiving the national dex and delivering the ruby and sapphire to celio.
If you use VBAlink, then yes.
its probably cause you don't have the national dex in emerald.
only when you get the national dex on Sapphire version
Migrate Pokemon from your older games like emerald, firered, and leafgreen. Have a nice day!!
Yes, if you trade it you will automatically get the national pokedex on Pokemon Emerald
Yes, I'm pretty sure, but you will need to gameboys and a connector cord

Ruby, sapphire, another emerald or firered and leafgreen. Must have national dex for all games and for firered and leafgreen you need to get the ruby and sapphire and give it to celio on one island.
