    Right, so it captures the data which is being sent to the YM IC on your sound card, rather than the sound coming out of the YM chip, yes? And then presumably some bit of software can then replay the captured data through another YM chip, and by doing that you get the actual original sound being played by an actual YM chip, rather than a recording of the sound being replayed. Am I keeping up so far?

    It captures the data, which is converted to a raw waveform (raw PCM signed, 16-bit little endian, 49716 Hz, mono), which you can then open in your audio editor of choice. I personally use GoldWave to trim the files and save to WAV, and Audacity to encode them to MP3.

    Looks like the most difficult part would be the acid etching, has anyone done a run of boards for these? I know that there are OPL via parallel port devices available out there but those output audio rather than raw digital data.

    BTW, for anyone wondering if there is any value-add to these files whose songs you might have heard before, there is: DeathAdderSF has named them all, and added MP3 tags for title, game, and composer/contributing artists. These are drop-ins for your music library.

    If you can get to grips with a free PCB design package like 'Kicad', the output that program produces can be emailed to any number of PCB makers in China who will make you a little batch of them for surprisingly little money. They are so cheap that it is hardly worth mucking about with UV-resist PCB and Ferric Choride, then a PCB drill.

    The days when having a one off or small run of PCBs made would have cost hundreds of dollars or pounds are long gone. The price now is more like $20 or less for a batch of five, even for double sided PCBs which are quite hard to produce by hand.

    There is usually a carriage charge to add to that, but even then the price is not bad.
