I was responsible for the OPL3 FM-synth music on a newly developed DOS game called SLIPSPEED. I thought it would be interesting for people here to read a little about the background of this project, so I wrote some words about it: https://martijnfrazer.nl/slipspeed-radical-music/

If you want to see & hear the end results, I filmed my screen running RAD Tracker 2 (which is what I used to create the music) and put it here: https://www.youtube.com/playlist?list=PLwuFnV … 8SJmYk-Azd0riu3

The game itself can be found here if you're curious: https://voxel.itch.io/slipspeed

Thanks! I tried the share version on my celeron DOS pc and it works well, very nice.
Could not get it to work with opl3lpt (adlipt driver), i think because your game uses protected mode (through CWSDMPI).
Would you consider supporting opl3lpt ?

I'd love to support OPL3LPT, but I'm not sure what would be involved. We're currently using RAD Tracker v2, which comes with a playback code example. The game itself is written in C using the Allegro library.

Any idea what to look for in order to support OPL3LPT?

Hey
have a look at the OPL2::write function : https://github.com/pdewacht/adlipt/blob/maste … st/OPL2.cpp#L89
this works for opl2lpt and opl3lpt

Does the game have complete adlib support ?
-->I mean, are the sound effects also played through adlib card?

No, the music is composed for OPL3 chips (such as found on the SoundBlaster 16). The sound effects are all PCM audio.
