I have been looking into this, and it seems a number of NDS games distribute NDS ROMs (Convenient, right?)
through DS Download Play, along with some Wiiware games.
The downside? no experience in coding, coupled with a lack of initiative limit me so far as research and wishing.
However, http://gbatemp.net/threads/ds-download-play-send-nds-file-with-planet-puzzle-league.306625 (http://gbatemp.net/threads/ds-download-play-send-nds-file-with-planet-puzzle-league.306625this) this proved some useful information that could turn this into a reality.
The thread 404'd, mate.
