#Interlace problem
Hello… This is a simple question, but through my lack of patience I've
decided enough is enough <smile>.
I'm having problems reading the Vertical beam position while in interlace
mode, and blittering a 4 bitplane image. It seems to me that I could wait
till the beam was at the bottom of the screen (during the even scans), then
blit in the image, but it still flickers <sigh>. What is the trick in
blittering in interlace. Isn't the LOF-frame flip-flop in VPOSR suppose to
indicate if the lines being scanned are Odd or Even? Please help….
Thanks… David
