Research notes based from here:

I can't remember who it was that brought this to my attention on the IRC (maybe tails_), but a while ago I wrote a python script for pulling out the instrument data, into files we can use in existing programs.

The PC98 version of Win95 had a MIDI driver for the YM2608 which included its own patch set. According to the blog link, it was also present in another thing (BIOS???) but I couldn't quite make sense of it.

Anyway, I've already ripped out the instrument map from the respective DLL and you can find my script (along with output files i attempted to create from it - OPM bank for VOPM, and an FMMIDI programs.txt) here: ... ch-src.rar

TFI conversion of the instruments as well as a VGM MM project template with all the patches imported, can be found here: ... ch-TFI.rar

EDIT: Interesting note - Playing MIDI's with the patch set in VOPM need to be transposed down one octave. This probably suggests the driver itself played all notes at a lower pitch. (No way to verify with lack of an actual machine :P)
