Gave it a quick try on my Ubuntu box. It's free, so what the hey. At first I had libFLAC.so.8 error. Cleared that up with: ln -s /lib/x86_64-linux-gnu/libFLAC.so.12 ~/GOG\ Games/Jill\ of\ the\ Jungle\ The\ Complete\ Trilogy/dosbox/libs/x86_64/libFLAC.so.8
Fun game. The arrow keys didn't work, so I used the ones on the number pad, little awkward. You weren't kidding about the soundtrack.
I know...for a freeware game it had some bangin' tracks.
Do you know a way to play these without actually playing the game?
Many years ago there were rippers to take the CMF files out of the actual program code, since they're essentially just in there in compartments. Those were all back in the days when DOS 5.0 was still king, I don't know how you'd go about finding them these days.
I probably still have the episode 1 files somewhere, I will take a look this week and see if I can locate them.
