Where do you find the game ID and game code for Pokemon Conquest in order to get Action replay stated for your Nintendo ds?

Action replay codes are actually passWords,u go 2 the menu and hit "PASSWordS",then type a passWord and a messenger will come and tell you,depending on which passWord u type,and she'll tell u there's a swarm of,say,misdreavious,in the place ur at.Then u have to go battle the pokemon,and if you;re able to link with them,you'll have a new partner!
