Convert Snow Bros drums to melodic channels.. and then to midi.?

[Wanny]

The title sounds messy, so let me explain.

I again want to convert the Snow Bros music (that uses the YM3812 chip, aka OPL2) to MIDI, and the tracks have a couple of little problems:
- The Bass Line is in the DRUMS section as the BD part.
- An addicional melodic instrument is also in the DRUMS section as the TOM part.

So, if I try to convert them using VGM2MID, the pitch of those instruments is completely lost.

Is there any way to turn those drum tracks into regular instruments?



As a bonus question, how was the Snow Bros music ripped to VGM in the first place?
