Ok, to the instructions...this is the Pokemon modifier, and if you press L+R, you'll get 493 master balls, but only one problem, it deletes the first item in your bag, so make sure you don't have something important there! Then toss out EXACTLY 116 masterballs and you'll get 377 masterballs (the pokedex number of Regirock), now go into the grass and hold down L and there should be Regirock! If Arceus shows up a few times, don't get angry, make sure you have thrown out enough pokeballs and then keep on doing it until Regirock appears. By the way, Regirock will show up at the level of the natural Pokemon who live there's level, so if you like to have him strong first thing, go to a place where there are strong Pokemon, if you want to be proud and raise it up to a high level, go to Twinleaf town to get him at level 2! By the way, this works if you want other Pokemon too, if you want Shaymin throw out one masterball! The number of masterballs has to be that Pokemon's pokedex number in order for it to show up! =) By the way, if you use the modifier and get Regice and Registeel, you can go to the Snowpoint Temple (only accessable by defeating the Elite Four) and get Regigigas, but you must have Registeel, Regirock and Regice in your team in order to battle him (plus you may use the masterballs on normal Pokemon to catch them without having to battle)!
