The YRW-801M instrument ROM is already dumped. Could you peel off the "MIRO" sticker on the chip at U12 and see what the markings are? (It'll likely be a micro controller of some sort).

Ahh, ok. So yeah, there's likely nothing to dump from that outside of the instrument ROM. The 82c929 is an HLE SB16 + CD-ROM interface (a data sheet with register programming info is available), the AD1848 is the DAC for the SB16 audio, and the OPL4 handles the rest. So we don't need the card itself for emulation, just the drivers and whatever other software came with it.

Drivers and manuals are on the site I linked to:

http://www.mirosupport.de/sound/pcm10/pcm10.html

They also carry files for the PCM12 that has a built in MIDI port and can support a wavetable extension

http://www.mirosupport.de/sound/pcm12/pcm12.html

In a later incarnation it was PnP compatible

One of the most famous demoscene Easter Eggs. Great soundtrack on the demo itself too.
