Disclaimer:
I know your not _suppose_ to directly write to the screen but this is
a game and I want to. (At least I make sure the monitor is in B&W.)

Does anyone have any code/tips to copy and bitmap to the screen with
zero flicker? I wrote an assem routine to rotate the bits of a bitmap
left to right to align it to the screen but the calculations and
algorithm in copying the words to the screen seems very complex.
I need to support rectagular clipping and any size bitmap. I'd also
like to figure out how to do this with a background (maybe a changing
background).
