Site updated!!
look at:

http://ragozini.googlepages.com/vdpenc

Now VDP limitations are taken into account, but the k-means and the VDP "quantization" are in cascade
I need to speed up a lot the VDP "quantization" in order to include it in the k-means loop
only in this way we can really improve WRT the standard bmp->scr2 converters

BTW, how does the preliminary result look like?
IMO it looks non excellent but convincing ...

The right side should be pure MSX1 screen2 !!
(at least I did my best to include in my code all the limits of MSX1 - tell me if the color clash and the palette are wrong)

PS
the msx1 palette i use is (in RGB) :

pal = [ 0, 0, 0
        0, 0, 0
		0, 241, 20
		68, 249, 86
		85, 79, 255
		128, 111, 255
		250, 80, 51
		12, 255, 255
		255, 81, 52
		255, 115, 86
		226, 210, 4
		242, 217, 71
		4, 212, 19
		231, 80, 229
		208, 208, 208
		255, 255, 255 ];
