Riolu(#447) is a Generation IV(#1-493) Pokémon and Emerald is Generation III(#1-386) therefore you can't obtain it there.
sorry, you can't get riolu in Pokemon emerald version.
No,You can't.There is even no Riolu in Emerald and even to all 3 first Generations (Yes,including the Emerald.)Riolu and Lucario only appears at Generation 4 and above Pokemon games.
Lucario is a 4th gen. pokemon, therefore not available in emerald, which is a 3rd gen game.
He is a generation 4 pokemon, and therefore not obtainable in emerald
Ash does not get riolu but it does follow him in Pokemon ranger and the kidnaped riolu and Ash wants to bring him back so he does alitle bit.....
You can get riolu by releasing 5 lucario's at the release point you will get a riolu ticket use it at the recruit point to get riolu.
At this point in time, Lucario is its final form. It does evolve from riolu.

If you want riolu to evolve, make him happy
