Before you can trade you have to finish the game COMPLETELY and retrieve those things for helping the professor with the PC (later in the game) and once that's done you can only trade accros regions on that island so if you re begining it s a LONG ways away it s hard to finish
You can just breed your starter Pokemon with a ditto to get a egg of your starter Pokemon in Pokemon leafgreen or firered then trade them.
You have to trade eevee to a game with a time system (ruby, sappire, emrald, gold silver crystal, diamond, pearl or platinum) and raise it up at night.
Its impossible. The only way to get a moltres is to get it in pokemon leafgreen or firered and catch it on island 2 (I think). Then you beat both games (beat elite 4) and finish pokedex in pokemon firered/leafgreen. Once you did that, you have to trade moltres into emrald. You can only do this with gameboy SP's and regular gameboys, and you need a wireless connecter (or with wires, doesnt matter). thats the only possible way to get moltres in pokemon emrald. Hope it helps!!
trade with fr/lg... there is no other way
trade from fire red or leaf green
if you have another Pokemon game and have a pikachu in that game you can trade it from that game to emerald
Migrate from Ruby, Sapphire, Or Emrald. Or trade from a friend
Maybe, if you pal park one from Fire Red. THERE ARE NO +++++++ MURKROW IN FIRERED OR LEAFGREEN OR RUBY OR SAPPHIRE OR EMRALD!!!!!!
trade it. There are no houndours in firered.
Slowpoke is not in firered only leafgreen can get it trade one to firered to get it.
In Pokemon firered you can't, but in Pokemon leafgreen you can get it then trade it to Pokemon firered.
You must trade pinsir from leafgreen to firered.
