Spoike 445e7f476b a dos port, as a dig at eukara about his xbox port project. 
mouse+kb+soundblaster devices should work.
you can compile a dedicated server, but the lack of any networking support makes it a bit pointless.
the software renderer will work, but its crap and gets absolutely dire framerates.
there's no code to init mesa or anything, so its crappy-software rendering only.
I doubt anything useful will ever result from this, but it was still interesting to do. possibly the only useful thing to come from this will be from limiting ram use.

//a note about dedicated servers:
//In the server-side gamecode, a couple of q1 extensions require knowing something about models.
//So we load models serverside, if required.
//things we need:
//tag/bone names and indexes so we can have reasonable modding with tags. :)
//tag/bone positions so we can shoot from the actual gun or other funky stuff
//vertex positions so we can trace against the mesh rather than the bbox.
//we use the gl renderer's model code because it supports more sorts of models than the sw renderer. Sad but true.
