Can I take this time to interest everyone in a a free game/engine?
nuQuake is 100% free and had binary releases since day 1.
It's a mostly compatible, fairly well performing quake 1 engine running in beautiful 640x480 VGA.
Loads most mods and generally hangs around 30fps, supports controller and keyboard+mice, as well as all the stuff you'd expect.
And! If something doesn't work, just let me know and I'll see about fixing or adding it.
Also, Corbin does care about the game, but I'm not sure why this issue has taken over a year and a half to find.
