You can't catch wild Treeko in Pokemon Emerald. You need to choose it out of the three Starter Pokemon that are offered to you at the beginning of the game: Treeko, Torchic, and Mudkip. to see it, battle rival or other trainer
Pokemon Emerald Enhanced is a hack of Pokemon emerald. The most special thing about it is that all Pokemon are available somewhere in the game. No trading or gamesharking is necessary. Toward this end, a few new areas have been added as well. As a final note, the three starter Pokemon for this hack are Zapdos, Articuno, and Moltres.
The three legendary Pokemon in Pokemon emerald is Kyorge, Groundon and Rayquazer.
You cannot without a cheating device such as the Action Replay. Sorry.

Torchic, Mudkip and Treecko
There's three starter Pokemon in Emerald, but you can only choose 1. The starter Pokemon are Mudkip Water/ground, Torchic Fire/fighting and Treecko Grass.
You can only get one of the three Starters in Pokémon Emerald without use of cheating or trading. You can trade or use an action replay code to get all three (I don't know the code, so I can't help you there). Hope this helped.
You cannot possibly get all three. Only one without a hack.
you don't you get them from emerald or firered/leaf green
You can't! You'll have to trade with someone, as in Emerald, you can only have one of the three starter pokemon.
Yes

There is no other way.
It is impossible to get all three starter Pokemon in one game without trading, unless you are willing to use an Action Replay.
