I'm writing my first game in Djgpp and I'm trying to use Mode-X because of
the many advantages. The only thing I don't like is the non-linear
addressing. Whenever you plot a pixel you have to select the bit-plane
right?! Okay I wrote a function to do that, but obviously it is somewhat
slower than say a 13h function. My biggest problem is blitting. How can I
blit in mode X without plotting one pixel at a time (as apposed to a say
memcpy command to blit whole lines). Basically I want a fast and easy way
to copy a buffer containing an image to the video buffer in mode-X. Maybe
that's not possible, maybe I should try VESA programming?? Any help would
be appreciated.
