Do you know by any chance what algorithm for dithering Photoshop is using?
And could you try to do the same thing to the jinxter bus picture?
You might want to take a look at Ungif. http://www.dilwyn.me.uk/graphics/ungif.zip
It does dithering in mode 4 and 8 and runs on any QL but was used here on QPC2 in mode 8 to make this example.
A DO on the converted image opens a menu to change settings and redo the image.
This size is 512x256, but it can be adjusted to trim the automatic border later.
