Lost all my demos, so... next best thing. This game is from some cpmduel cup final.
Testing this graphical config.
I don't have the exact configs but these should be close enough:
cfg: http://pastebin.com/r9aqCCVi save as a .cfg file to cpma dir or baseq3 dir and load it with /exec filename
hud: http://pastebin.com/KXXpas73 save it to cpma/hud/liskhud.cfg my cfg will load it, or /ch_file liskhud.cfg; reloadhud

The textures are just r_picmip 10 no retexturing or anything.
