I wonder if anyone can help me with a puzzling problem I have. I recently started trying to program the blitter, directly writing to the hardware registers just for fun. No matter what I did I never saw anything on my screen (I was trying to line draw). Quite by accident, I discovered that if I used Move() and Draw() to draw a line on the screen before using the blitter, the line I was trying to draw with the blitter appeared! I'm guessing, maybe Move() and Draw() initialize the blitter somehow and I'm missing the info on how to do this. Anybody got any ideas? Anybody got any source code for using the blitter directly like I'm trying to do? Thanks, Darren Burns
