No, and some feel that the different resolution of the 3DS actually causes some loss of image quality due to scaling, compared to DS Lite and DSi/DSi XL.and would there be a down side to using a ds lite instead of a dsi or 3ds?
like how using a psp 1000 would cause a slow down in some newer games.
DSi and 3DS run DS games/flashcarts in "DS mode", and no DS flashcarts that are currently supported can take advantage of any other hardware (Aside from using expansions in DS Lite/Phat Slot2).
