If you have a pokemon gba game, ruby, sapphire, emerald, etc, in your ds while your playing diamond/pearl, different pokemon appear. Now I don't wanna spend over 100 dollers on every pokemon game thats for the gba just to, catch em all. So is there a patch for a nds rom of pokemon diamond or pearl that simulates you have a gba game of pokemon in slot 2, even though you dont?
