You talked to the professor after beating the battle tree 5 times to unlock the option screen button to turn shinys on, right?
Google is your friend buddy, odds are 1 in 8192. If you had the shiny charm in OR, you must have played a while, yes? Or you hacked it in, and didn't play the game at all. See, you actually have to ENCOUNTER wild pokemon for you to even have a chance :^) Either way, it takes a little bit of luck and a whole lotta time. The first shiny I ever found was in platinum, and it wasn't till I chained for one. This gen however, I've gotten super lucky and found 2, chained for 2, and bred one in 20 eggs.
