Action Replay codes are not pre-configred when a game comes out. They are reassignments of memory locations for the game and are created after the game comes out. New codes can always be made for a variety of purposes. Your best chance to get the codes you want is to search using Google or another search engine (but beware that some codes may not work and may damage your game and/or save if entered incorrectly).
