These files were created in MilkyTracker and packed into a binary voxatron.dat file. They were extracted using the tool mediaextractor (hosted in GitHub). Presumably to minimise file size, all of the instruments were held in one XM, inst0.xm and each other XM contained a reference to the instrument. I have painstakingly restored the instruments, so the tunes play normally :).
