@all:

Has'nt anyone noticed that the internal DCE flickerfixers and the CV64/3D scandoubler uses just 4-bits per colour on the green and blue channel and only the red channel uses 8-bits? Try colouring a large portion of the screen (using ntsc or pal ofcourse) in a aga-aware paint-package as Brilliance or DPaint5, select that colour in the palette-editor and play around some with the red, green and blue sliders...

Daedalus:

The internal DCE ones as well as the CV64/3D scandoubler does have the 8:4:4 limitation. The reason for this limitation is that it only needs 2/3 as wide/much buffer-memory that way (16-bits wide for 8:4:4 instead of 24-bits wide for 8:8:8).
