Dawn Patrol was amongst my first WW1 flight "sims" ever too, I can`t remember if I ran that or RB1 first.
I still own the very first PC I ever had, with DP and RB1 on it.
But I prefer to play it on Dosbox w/D-Fend.
Remember to install the game WITH dosbox (Or, practically D-Fend) and install as VGA res, and not SVGA or you`ll end up with the usual error when starting the game, however if anyone knows how to get the game running with SVGA please do say so, I havent played DP w/SVGA textures in YEARS
Set up with Sound Blaster for sound, preferably 16 or the likes.
I sort of missed out on Flying Corps, also it is very hard to get running whether it be dos box w/d-fend or W7, RB2 was pretty good though
