Is it possible to obtain shiny pokemons in Emerald / Ruby / Sapphire?
yes it is i have a shiny oddish.
Oh wow. I guess I really am unlucky. I haven't encountered a single shiny pokemon yet even after i defeated the Elite 4.
It's OK, Swift, neither have I. And i've played them all!
The chance of getting a Shiny to even appear in your game is 1/8192 so yeah.
