Indivision AGA issue

[alexh]

You are using the latest firmware? Switched off scan-rate conversion (i.e. set it to 1.0)? Still getting problems on a CRT?

All I can think of is it must be a faulty Indivision AGA, perhaps with a broken RAM.

scanrate set to x 1.0 works but then I'm limited to 50hz refresh rate

I think this is a case of "Tough! That's just the way it works". Anything other than 1.0 and you're going to get the glitches when horizontally scrolling. Promoting 50Hz to 75Hz (1.5) will minimise it but it will still be visible. I don't think Indivision AGA can do 2.0

Only work around which will work is to keep scanrate set to x1.0 and use WHDLoad to promote the game to 60Hz using the NTSC tool type.
