@plimbs it seems that someone will need to go on github and ask the devs for xash3d about it.

thats what i did to get it to compile again with the script from zerojay.
now i have a pi4 and i have not tested it yet. so im not much help on this

and i used the old way to get it working on my Pi3, and that way uses the old version from FWGS

For me personally, Quake 2 is my favorite of the Quake games. Most hardcore fans seem to look down on it but I really think its co-op gameplay was a particularly strong element.
