Catch all 202 Pokemon in your Pokedex, then go to the hotel in Lilycove City and talk to the Game Designer. No, that's how you get it. From what I've heard, it's simply a reward for the player for completing your Pokedex. Catch 200 Pokemon and talk to the Game Designer. All it is is it shows you a certificate. I thought it was something good but it wasn't. Depending on which game you have, catch all the Pokemon in it and see the Game Designer or (in later versions) the Professor.
