Yes there is, I'm pretty sure "card swapping" doesn't work on the DS. That's how people knew the fake DQIX cards were fake i nthe first place (other than the game not veing anywhere near completion).
Im pretty sure it would work if save data was stored on a GBA cart. Straight swapping wouldnt work as the DS turns off when a cart is removed.
