When DOSBox displays text screens (and maybe some graphic screens?) in full-screen mode, the actual DOS window is inside a "frame" that is entirely black.
I've tried to figure out how to change that frame to a specific color, but I can't find the place in the code where I could do this. I'll be very grateful if anyone can tell me either (1) where the full-screen "frame" is specified as black or (2) what code I would have to add to specify a color.
My guess is that this seems to be set in sdl_gui.cpp, but I don't have enough knowledge to figure out exactly where or how.
I am NOT asking about setting the background color for the DOS screen itself (in the way that ansi.sys sets the background color) - I am asking ONLY about the black frame that appears when DOSBox is running in full-screen mode, the frame that extends from the outer edges of a DOS window to the margins of the actual physical screen on the host.
Thanks for any help with this. What I hope to do is add a config setting to my custom build that would let the user specify the background color with RGB numbers or something similar, but first I hope to figure out how to hard-code this color, if that is possible at all.
