For this fixed charset some grafics are really NICE!!!!

Is it possible to put 4 dots (4x4 pixels) with 4 different colors at one 'charsetpoint'?

With the actual CGROM? only two colors.

But with my prototype extending CGROM to 1024-character font (using D3 in attribute VRAM to select between two 512-character fonts), I created a 256-semigraphics with "4 grey levels":

Nonetheless there is a trick to use character swapping per raster line (pixel line) just before the screen displays that pixel line to draw graphics. But it is limited to 112x200 pixels as we can swap 14 characters per line at most in PAL version.

If not well synchronized with the horizontal synchronization (here NTSC doesn't cope well above 11 characters per line), it gives:

There is even a more elaborate drawing using the same technique:
