You might want to talk about this on the podcast, some info you might find useful:
This game uses John Miles Audio Interface Library 2 drivers. The drivers have the .ADV extension, music files are .XMI and voices are .VOC.
The game supports PC Speaker, Adlib, Sound Blaster, Sound Blaster Pro and Roland MT-32.
For the people running DOSBox i recommend setting the OPL for Sound Blaster Pro 1, this game has a stereo dual OPL2 soundtrack, and it sounds better with that than if you have the OPL set to Sound Blaster Pro 2, since it will try to simulate an OPL3.
And no, an OPL3 alone can’t replicate 2 OPL2 chips, it’s just not possible.
For people using real hardware, if you don’t have a Sound Blaster Pro 1 card and instead have the original dual OPL2 Pro Audio Spectrum all you have to do is to select Sound Blaster Pro for music and then replace the SBP1FM.ADV by the PASFM.ADV driver. Essentially your Pro Audio Spectrum will play the dual OPL2 soundtrack just fine. For speech the same can be done, replace the SBPDIG.ADV driver by the PASDIG.ADV.
Needless to say, the voice acting is extremely cheesy, tries to be almost Shakespearean but ends up being cringe as f.
For the Roland devices is better to use the Roland CM-32L, or the internal ISA version LAPC-I (it’s the letter I for IBM not the number 1). The reason is that the CM-32L/LAPC-I devices have an extra 33 sound effects that are used in the game. The Roland MT-32 will play the soundtrack just fine, but during the game these specific sound effects will be missing where they are used.
