Well I butchered the main VPs a while ago to try and get closer to standalone status.
That seems to be a source of many of my problems.
My mod.ini already looks like so:
[launcher]
image255x112 = fringespace.bmp;
infotext = This project is designed to duplicate, as closely as possible, the "feel" of Tachyon: The Fringe, to the Freespace 2 game engine. Tachyon was always plagued by bugs, hacking, and lack of updates. This mod is an attempt to rectify most of the egregious problems, and to update the playing experience for Tachyon fans. ;
website = http://fringespace.org;
forum = http://fringespace.org/index.php?name=PNphpBB2&file=index;
[multimod]
secondrylist = ,mediavps;
So I'm going to assume that's fine.. since the major parts are the same, probably go and get turey's installer again and redownload the VPs.
Eventually I guess I'll need to figure out which files control the shaders, then keep those separate.
I go get this done, see if everything reverts to normal.
