KazoWAR updated “NDS Music Player”. It’s based on fincs’ SSEQ Player and allows to play music tracks from commercial games with a GUI browser pointing at the desired ROM file.

Release notes:

Updated again, this time SSEQPlayer, to make 100% certain that EVERY valid SPS file is correctly listed. As a side effect, if the rom file for which an SPS belongs is moved/deleted, then the SPS is no longer listed in SSEQPlayer.
