- Hello
- Is it possible to scroll a scandoubled screen (DBLPAL/DBLNTSC/MultiScan etc)
- on AGA, smoothly, in the X direction?
- When I try it, a wide strip of the left side of the screen disappears until
- the screen has been scrolled enough to the left. After that, another strip
- disappears, etc.
- (Try opening a wb screen bigger than your overscan area, and scroll around).
-
- If this can't be dealt with, how is it then possible to write OS compliant
- games/demos that must scroll their screen smoothly in the X direction?
-
- (Oh, when using a PAL or NTSC 15Khz screen, everything works fine)
-
- Cheers
- Irmen
