Unfortunately, we cannot download ${name} automatically.
Please purchase a legitimate copy of Quake 3 and change into the installation directory.
You can either add all relevant files to the nix-store like this:
mkdir /tmp/baseq3
cp baseq3/pak*.pk3 /tmp/baseq3
nix-store --add-fixed sha256 --recursive /tmp/baseq3
Alternatively you can set services.quake3-server.baseq3 to a path and copy the baseq3 directory into
$services.quake3-server.baseq3/.q3a/
