mpdDS is an open-source mpd client developed for the Nintendo DS console.

Release notes:

I have uploaded a new build, compiled against dswifi 0.3.3. So MPDDS should now work fine on all Nintendo DS, even the latest Nintendo DS Lite models with the new firmware, and work with all router setups too.
