While playing the game, press L and R

In the Bag, you will find 493 Masterballs, the 493 means the Pokemon number, therefore in this case Arceus would appear in the wild grass.

To get a specific Pokemon, Just keep the amount of the remaining Masterballs equal to the Pokemon Number (To get Bulbasaur, through away 492 Master balls, which would only make 1 Master Ball available; #001 is Bulbasaur's Pokedex number) (When you through away the master balls press L once or twice so you will the pokemon you want)
