Not trying to hi-jack the thread, however here is a great mod addition for Red Baron 3D. Great game.

I especially like the Resurrection mod, allowing the aces of the time to die randomly, if at all...
Here is a site that has a NO MARKERS download for CMBB and CMBO... Go to the MODS / EFFECTS link and viola. Not sure if they will work for CMAK though. I guess check the bmp#'s. Hope this helps.
