I doubt that this request is possible on the DOS versions of the games... but are there any mods that allow the flight cache to be bigger than 2048kb? It's really annoying that you can't record long missions in their entirety using the Flight Recorder, like the A-Wing historical mission where you blow up mock X-Wings, A-Wings, and Y-Wings.

edit: Oops...turns out the Windows Flight Recorder system is different from the DOS ones...no clue about the Mac ports though.
