I'm interested in the newly raised questions about the check board mixing of colors and the behaviour of it on a real machine and let's say a 1084S monitor.
It seems most of the similar color blends in horizontal axis has been resolved, but not all of the vertical artefacts (or even diagonally and so on).
I remember that if one dithered black with extremely bright colors, the field could really stand out more (usually being heavily darker than what it would seem in emulation).
In a non-emulation it would probably look like the black color wasn't any different from let´s say dark grey or even middle grey part from the joining hm... Cyan?
It would be of interest if anyone could emulate to particularities from the real machine, and I do remember that they are even greater in hires.

Does anyone know how to use VICE on an external screen?
Im trying to run it on my PAL 50Hz television but VICE
insists on running on my monitor instead. I've got
multiple outputs on my video card and would like to
use my TV as the main monitor for VICE instead..
(for even more true PAL emulation!) ;)

Has anyone used recent build of Stella (Atari 2600 emulator)? There have emulated plenty of video signals and IMHO they did this right. Maybe WinVice should borrow the algorithm? ;)

WAT? ;) Not only, pay attention. Vice so far cannot emulate well those 'shadows'. Also greenish vertical gradient bars on light checkerboards are not handled well whereas Stella has no bigger problems here. To my eyes, Stella takes more details into account.

If you have a beefy computer, check out Micro64 and turn on the full PAL/CRT emulation :-)

Wow, I wonder how much "beef" you would need to use this properly. Time for a new tower anyway after 3 or 4 years :)
