hi guys,
yesterday I jumped into foreign waters -- I need to code some HBL stuff ;-)
After some expriments I've got quite a stable HBL interrupt -- just simple not.l $ffff9800.w on every line. However, it doesnt look very well. Lines are, as I say, stable but near the left edge I see some (about 1 cm wide) flicker area -- when I try it in lower (320x240) resolution, "flicker area" gets closer to the left edge.
It reminds me very similar behaviour on 8bit atari when I didn't do vertical sync (using sta vsync instruction) before some color stuff.
So I'd like to ask what the hell I should do to fix this. I remember some article about disabling nearly everything (timer c, d, ...) but I don't like it very much (it should affect system as little as possible).
Could you give me a hand? ;-) Thanks in advance.

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
