Title: Amiga 600 shaking picture problem
Post by: Nicole Judith Ridgway on October 08, 2020, 06:48:04 PM

My A600 has always had this "shaking" problem.
It happened back in the days when I used my A600 with KS 2.05 and HDD,
and it happens nowadays with a Vampire and a 1mb ChipRAM installed.
My A600 was recapped some years ago but again...It also happened 25 years ago.
Has anyone ever had this kind of problem? Please let me know.

You might want to add more informations, like which video output you use, or the details how the shaky picture looks like, or even a video? :D

Ok, did see the clip.
Is it only with this game?

[Ian Stedman's mod] RGB Scart. But it happened also when I had RF out, and also with composite.
It happens also with other games (original and cr4ck3d)

And with Workbench too?

I will try as soon as I can.
If I remeber well it didn't do that.

Maybe try swapping out your Denise chip to narrow it down.   Or it could be an Angus copper problem. The Workbench question is a good one as that will isolate a timing sync problem.
