hmm since i am loading to internal memory i just threw the shareware version on there. i cant imagine they (sdlquake devs) would tamper with the pak file or limit it to shareware version... did you copy both pak0.PAK and pak1.PAK (for full version) ? perhaps resources are needed from both.

the gfx file should be in the shareware pak file... they might have moved a resource from pak1 to pak0 to make the shareware pak. its an archive format with tree structure inside... although winrar cant read it now so im not sure what format.

Edit : Glad its now working for you.

For some reason, the file it keeps its settings in (config.cfg) is being copied into /tmp/id1. If you want to adjust key bindings, for now you will need to set write permissions on that directory or copy into there as root.

I also rebuilt the program to accept dpad enter when it asks you if you really want to quit the game. My zip file was made on windows so chmod 755 before running. Most other options should be editable via cfg files until real build is made.
