How can i make pokemon games better?

ok my sister was playing a pokemon game and i watched her play it. i've seen the show befor and the game can be a whole lot better. so i want to create a better cooler and more attractive pokemon game(not saying that the games out now are really bad) but i really dont know how and want nintendos help since they have created the preveouis ones.can anyone give me advise or if you work for Nintendo or the pokemon company consider my idea. what sould i do?|||u should study the games then at a store like target,wal-mart,ect. buy a gameshark or action replay and buy a computer rom disk illegily and do it. any way it is illegel and dont do it
