@Dinierto Did you get an answer on this? I have the same problem.
I can't even get sound/cdtracks to get picked up by Darkplaces. Which folder did you put that within - mine is sitting in /home/pi/RetroPie/roms/ports/quake/id1/sound/cdtracks - but I've tried /home/pi/RetroPie/roms/ports/quake/id1/id1/sound/cdtracks and /home/pi/RetroPie/roms/ports/quake/sound/cdtracks also
Did you have to do anything else for that to work?
Edit: I've got this working now, I have .ogg files and .MP3 files in home/pi/RetroPie/roms/ports/quake/id1/sound/cdtracks and they are picked up in Darkplaces.
I've also got lr-tyrquake working, the same files in home/pi/RetroPie/roms/ports/quake/id1/music
I don't know if the original .ogg files I had were bad, or if having the .MP3s in there makes a difference, but it is working whatever the problem was.
I loved quake2!
The map indeed was q2dm1 'The edge'. The rail gun was in the room under the water.
How do you play this game now? What does it play like- I remember this making me invest in more ram and my first 3dfx card for the first time. P166 and 16mb of ram lol.
There was an online game called Red rover that was excellent. Also loved the servers that had power ups Haste, Vampire and some others.
Super shotgun, quad damage and haste was the most hilarious combination.
Thanks man :) Although, i'm not really a huge fan of the Roland Sound Canvas (especially the guitar sound). Anyways, i'll have a look at the PSX music. Although not 'authentic', it sounds more like 'real' music :)
On a sidenote, the SC55 pack features a track called 'bye bye american pie', and i can't help to think how much it sounds like a very well known Alice in Chains classic:
