Just some advice for anyone else trying to do this. I was trying to get Quake 1 to work on my retro system (voodoo 5) with mp3 music. This obviously requires a modern GLQuake replacement which includes a minefield of other things like graphical mods etc etc, I just watched to keep the game as stock as possible but with some added niceties.
My advice is using Requiem: https://www.quaddicted.com/engines/requiem
It is a modern replacement with lots of bug fixes, but keeps the game as stock as possible, plus the added mp3 sound I wanted. "reQuiem is a custom OpenGL Quake engine for Windows and Linux. It's designed for maximum compatibility with all things Quake - past, present and future. It's fast, reliable, and easy to configure. In short: it fixes what was broken, improves what needed improving, and leaves the rest alone."
Here is a link to the steam community with a great guide to getting music to work: https://steamcommunity.com/sharedfiles/filede … s/?id=118401000
This guy also includes high quality mp3 and ogg versions of the sound tracks.
Also it works well under Windows 2000. Every other engine I tried didn't work or crashed out due to needing a newer windows. So this version was really nice. Hope this guide helps anyone else looking to get mp3 music on a retro system with a modern client.
