Shiny AR code
On the forums, many people are complaining about these codes.
The trick is to encounter the Pokemon you want, in Shiny form, then TURN OFF THE AR, then catch it.
Note: Sometimes, turning the AR on/off causes the game to crash, so as a precaution, save right after catching you're desired pokemon.
