Ruuvisca has released a Minesweeper game for the Nintendo DS:

I started to develop a classic minesweeper game for nintendo ds. I think this game is now 70-80% ready but there is still many things to do. I haven't got a change to try it on a real nds but it works on dsemu-emulator (also on dualis, but not fully. check info page for details).
