Hi

see image, this is what I get with dia416.pcs in STE mode tos 1.62, with 
a 416 pixel width window.

From what I see, the image is 400 pixel width ? Which would mean Hatari 
display 8 pixels more on left and right.

Regarding the left border, there's a hi/lo switch, so on real HW we 
would see black pixels I guess. In Hatari we see the color 0 changing on 
each line (so far Hatari doesn't emulate creating "blank" pixels when 
res goes Hi).

On the right border, there's no hi/low stabilizer (it's not necessary on 
STE), but here again we display 8 more pixels, showing color 0. Maybe on 
real STE the display really stops earlier than in Hatari, that would 
need to be checked on my STE.

Regarding the 2 extra lines at the bottom, it seems to depends on the 
various STF/STE models. Some STF could have a few more lines, but maybe 
STE always had 2 lines less. I would need to check that too on my STE.
For now, Hatari assumes the 2 extra lines are always there.


Doug, what is the width of the pcs image, 400 pixel ? Do you center it 
on the overscan screen by adding black pixels on left/right, and if so 
how much pixels ?

works fine for me using winuae cpu, but I have a more recent version 
where I made some changes for CE mode. Let's see what you will get once 
I push my changes to main repo in a few days.
