Another dithering method, using alternating horizontal lines. It would be better for CRT TVs, since those lines would merge in single colors. There's still margin from improvement in the line method, but it'll be VERY slow.
Fixed version (about half an hour to run) on the right. Dithering is not as good as the 2x2 dithering version, but curves are much better (no blocks). It's obviously seen in some parts of the image, such as the back jaw curve.
Wonder if somehow the line method could be combined with dithering? Within a line there can be multiple colours after all, perhaps this could achieve some further fidelity.
All these pictures look really nice btw 
. And although the dithering looks good, I also like the line aesthetic, like used in the Dioniso games.

I did some tests in the past and quickly discarded them. I don't think line good be used with dithering (one would mess with the other in terms of optical illusion). Personally I prefer the dithering method, but as I told, it's hard to compare since the line method would be better for very old equipments that I don't have anymore. 
something wrong happen with the last version Blitz Basic never output the .bmp and .scr screen.
