I'm dealing with an odd format here, and it seems similar to VOX ADPCM, 8000Hz, but it when played back as such, produces the most horrendous sound. It's definitely similar to VOX ADPCM or some variant thereof, but I've been trying to identify it.
Here is the raw file: http://www.sudomemo.net/wav/BGM.bin
I renamed BGM.bin to BGM.vox and ran
sox BGM.vox -t wav BGM.wav:
This is how it should sound: dl.dropboxusercontent.com/u/20459451/dsifull.mp3
Any ideas? This has baffled us so far. Here's some of the BGM.bin file:
