Ok, after a bit of tweaking, here’s my MIDI file: https://martijnfrazer.nl/dgc-doom/
I’ve tried converting it to Doom’s “mus” format, but the tool I found from like 1994 called midi2mus doesn’t run on 64 bit Windows 11.
But since Doom 1.5 and up support MIDI anyway, maybe there’s no point in a MUS file to begin with. I’ve tried this in vanilla Doom in Dosbox and it seems to work fine. That said, if people feel a MUS file is needed regardless, I suppose they can convert this MIDI file if they want to.
So yeah, here’s my contribution! Idk how to incorporate it into the community WAD, but I hope someone can take care of that. And I don’t know where it would make sense to play it, but I also hope someone else can figure that out haha
