Yeah, here's the link to the required engine again (quakespasm svn r980):

I'm sure more engines will support this pack with time.
Barnak, thanks for the bug report. that's weird fsaa would cause issues, but glad you got it working.
For linux users, here's a suggested command to build the engine from source:
sudo apt-get install libsdl1.2-dev gcc subversion build-essential libvorbis-dev libmad0-dev libogg-dev
svn co svn://svn.code.sf.net/p/quakespasm/code/trunk/quakespasm@980 quakespasm-r980
cd quakespasm-r980/Quake
make
Sorry it's a bit inconvenient, ideally there would be a stable Quakespasm 0.85.10 release already, but the timing didn't work out.
