ctrmus is a music player for the Nintendo 3DS. For now it plays PCM WAV, AIFF, FLAC, Opus and MP3 files. Due to limitations in ctrulib, only ASCII characters are displayed correctly. Other characters will appear garbled, but functionality is not affected.

Changes:

* Fixed an issue whereby Opus files would be played at the sampling rate of the original file that was converted to Opus rather than at 48000Hz which is what all Opus files use.
* Added support for Flac data in Ogg container.
* Updated submodules.
