* : This doesn't apply to the starter for exemple. Didn't test it a lot (but it seemed to work nicely on the grass). This code will create a 100% LEGIT shiny pokemon, ie. undetectable by anyone. However, as the code makes the game compute the 'shinyness' for you, it creates a small lag before every battle. And yes, you have to check your trainer card (press X, then select your trainer name) each time you reload the game, else the code won't work properly.

Better than the last 'walk through walls.' It does not cause you too stop for no reason.
