"Radastan" or "radastaniano" it's a non standard graphic mode designed by ZX-Uno.
It consists basically of 128x96 pixels (double size) and 16 independent colors for each pixel, selectable from the 64 of the ULA plus palette. Each byte contains 2 "horizontal" pixels (4 bits color) and are organized linearly. There are no screen thirds as in the original mode.
In this mode, each screen needs 64x96 = 6144 bytes instead of the classic 6912, because it does not use the attribute zone.
I think that the loss of resolution is compensated with the highest simultaneous color numbers and the abscence of "colour clash".
At present there are some demos and games in development for this graphic mode.
