I am attempting to decode the VTX music format.
My understanding from https://github.com/gasman/libayemu/blob ... format.txt is that the format has header information and the sound-sequence data is like the YM3 format. I found the YM3 data specification at http://leonard.oxg.free.fr/ymformat.html.
In the sample file, I was able to extract the metadata bytes from 0-136. It appears that bytes 137 to EOF are music. I think I am supposed to read the remainder of the file in 14-byte chunks to collect voice/noise/pitch data. But I do not understand how to interpret those bytes.
The first 14 bytes in the sample file are

Thanks! I'm happy that I found this forum!
