hmmm...
could someone do a preview of how it would look on a real tv when there would be two screens with slighly different dither or colors and exchange them at every frame for the shown game screen? But for the not-interlaced version... I'm really curious..because it should "polish" the dither somewhat...although I wonder how much flicker it will produce...
Please;)
If you have a monitor that supports 100 Hz or 50 Hz refresh rate, then it can also be tested with the emulator. Some LCD monitors do not advertise 50 Hz minimum refresh rate, but can actually still be forced to display it without problems. Setting double buffered video mode in the emulator, it will show the picture correctly with the flicker.
Another solution to display interlaced images on the emulator with 50 Hz flicker is to use the "resample to monitor refresh rate" mode. However, this does add some temporal blur, which smooths the flickering.
Alternatively, one can also speed up the emulation so that the refresh rate becomes 60 Hz, which is supported by all LCD monitors, and then use double buffered video mode. This can be done by setting the emulation speed to 120% (loading a text format configuration file that contains the line
vm.speedPercentage 120), or by increasing the NICK frequency in the configuration from 889846 to 1068750 characters per second.
EDIT: so this mode is: up to 16 different colors per line, but only 2 colors per 8x1, yes?
Yes, but only 8 of the 16 colors can be set separately for each line, the rest are defined by the BIAS value for the entire screen, and these colors are generally used less by the converter (because no matter what BIAS it chooses, there will likely be some not very useful colors on the palette).
