I tested with the 6bit dac of zxdos, and works ok.
I atach a photo of the screen. Dont show it very well, but show the shadow of the clouds.

I think I understand now, although dark grey is possible, clouds are rendered as solid light grey. Ideally they would be white/light grey/dark grey to be more like the original PCB, but core just assigns closest value.
so the screenshot (which I looked at when buying) is incorrect (and misleading).

Just to check a little bit more :
Clouds use sprite lut (rom) set x0C which give sprite colors x30/x31/x32/x33.
green-red rgb lut gives x00/xAC/xEE/x28
blue-green rgb lut gives x00/xB5/xBD/xA5
which in turn gives :
red : x00/x16/x17/x14
green : x00/x16/x17/x14
blue : x00/x16/x17/x14
which are 3 differents shade of grey for system with 5bits per colors.
x16 = b10110
x17 = b10111
x14 = b10100
For system with 4bits per colors 1 lsb is lost => x16/x17 merge into one single color.
For system with 3bits per colors 2 lsb are lost => x16/x17/x14 merge into one single color.
Anyway neuro_999 picture seems to have only 2 colors for clouds which is strange for 6bits system.
Unfortunatly I can't get zx-uno timepilot source code to check any further.
Best regards.

The source is in my git.
https://github.com/neurorulez/jammazx1/ ... /timepilot
I saw the problem. When downgrading video bits i use greater bits to pass to the dac... I will try to get lesser bits.
Btw in the 6 bit system i see all the grey shades... The problem is the photo with the mobile to the screen.

Thanks for the link to your source code.
I saw only 3 bits are used for 15khz and even only 2 bits for blue in scandoubler for 31khz (vga). You should extend to at least 5 bits if possible (required more memory for scandoubler)
Best regards

Buenas Tardes.
Para celebrar la salida de uZX1 he metido tres cores mas para el ZX-Uno, que son.
Eggor, Zig Zag y Frenzy.
Espero que os gusten, en unos días alguno mas vendrá.

Incluidos también el Centipede y el Donkey Kong.
Este ultimo hay que dejar la rom en la raid de la SD (fichero DKONG.ROM) ya que es demasiado grande para meterla en el core, y la carga a SRAM al inciar.

He publicado los del sprint2 color mod en mi git, asi Gehstock puede pasarlo a la mist/miste.

Y todos los cores que he hecho nuevos funcionan tanto en jammazx1 como en el zx1 normal. De hecho estos últimos los he hecho pensando en el uZX1.
