Can you send me a XEX of a screen so I can test it on my CRT?
Instead of DLI, you could simply use 5 color screens.
I will distribute an ATR file just before the week-end, please wait a couple more days.
I experimented with 5 color maps, and it was really poor. Frankly, they look better in 4 level of grey.
So with my system (16 colors flicker or 4 greyscales) I tried to strike a compromise.
People on Altirra/LCD will benefit from a much nicer palette, and CRT can fall back to 4 level of grey.
