I downloaded a copy of an old version of JFDuke3d that turned out to be a binary of JFBuild that could run Duke3d in classic mode (what I'm looking for) however, it had Duke it out in DC as episode 1, Hollywood as ep 2, Shrapnel City as ep 3, an The Birth as ep 4. So, I came to download a newer version in case mine was pre-Lunar Apocalypse. Turned out that it was also missing Lunar and couldn't run in anything other than Open GL. Which version runs classic mode and why is Lunar Apocalypse missing?

Maybe you have a fs*cked .grp. Have you tried a complete reinstall ?
