The Yamaha YMW258-F aka MultiPCM is the ancestor of the WAVE section of the Yamaha YMF278B OPL4, so there are a lot of similarities, but the conversion applies dynamic channel (re-)remapping to get the channel count down from 28 to 24.
The longer tracks need an OPL4 with 2 MB of sample memory, and sufficient system RAM as well.
And I also converted the other MultiPCM packs to OPL4:
I haven’t tested these as thoroughly as Daytona, but in a superficial inspection they sound good. Additionally, I think most of these are a lot lighter on the sample memory than Daytona is, some Wing War tracks require 1 MB and for the rest 640 kB ought to be enough.
Missing are Virtua Fighter and Virtua Racer; those use two MultiPCM chips and that’s a bit too much for our good ol’ MoonSound (and also my converter doesn’t support it).
This sounds amazing. I think an MSX playing Daytona music in a meeting is sure to turn some heads. I wonder, would it be also possible to convert Sega OPM+PCM packs (like Out Run, Power Drift, Super Hang On, After Burner etc.) to OPM+OPL4?
Should be. Though for those I would ideally add support to VGMPlay directly. But that may take a while still, so short term an off-line conversion may be a faster way to be able to listen to them.
