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.
