hbl on falcon
Posted by: mikro Sep,24.2007-16:32 

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.
