How do I make the OpenArena pk3s work with a vanilla ioq3 build?
By setting com_standalone 1 and the proper values for fs_game and fs_homepath : eg , in linux
I assume OA is installed in ~/OpenArena
cd ~/OpenArena
./ioquake3.i386 +set com_standalone 1 +set fs_game baseoa +set fs_homepath "~/.openarena"
But I've never tried indeed , I've used the same procedure with proper fs_game and fs_homepath values for Urban Terror to skip loading all the Q3 maps I have in ~/.q3a/baseq3 so to save lots of memory
