Action replay woes. HELP!

Right, this isn't going to be ANOTHER thread about getting action replay to work on flashcards, no this is much more interesting...ish. ;)
Do you think it is possible to use the ACTION REPLAY ON THE FLASHCARD to cheat on A REAL ds game. As in using actionreplay and then plugging in game? Y'know the way they used to do with the old action replays for gba.
Any ideas? ???
