Well, Lick has all but completely discontinued the Lick's Media Player that he developed for the DS. That, however, doesn't mean that we still can't enjoy some Media Player goodness.

In trying to come up with a way to finish Lick's Media Player, a GBAdev user named Lucas apparently managed to rewrite it from scratch through C, rather than the C++ it was originally written in. As he mentions on the their boards,

In the end, it became a complete rewrite. No more C++, only pure C. At ths time, I only have some basic functionality, WAV playback (files must end in .wav) and libmad playback (files must end in .mp3).

I need some feedback, if you can try, just download at http://www.cecm.usp.br/~lucas/lmp-ng/ . Theres two versions, a .nds and a .ds.gba. Both are compiled with libfat DLDI, so you can patch if your flashcart does not work out of the box. The source is also in the same page.

He also notes that this is his first homebrew, so there are bound to be bugs. Still, it looks (and sounds) okay to us, so what's not to like. maybe we can help him improve upon what Lick originally started, eh?
