The first time I played this I didn't have all the music. It was missing from the recruit screen and the mission briefing screen.

Then the music suddenly appeared, but the game skipped the title screen and the helicopter screen and I had a blank screen when the game started

Now sometimes it seems to behave and sometimes doesn't.

Anyone have any thoughts as to what could be wrong here?

So it seems that if I remove "INTRO.EXE" from dosboxCannonFodder_single.conf I no longer have this problem.
