How do you work this out ????

I was under the understanding that there are 8 Hardware sprites organised as
follows:

	Sprite 0 and 1		Colour Reg 16,17,18,19 = 3 colours + tranparent
	Sprite 2 and 3		Colour Reg 20,21,22,23 = 3 colours + tranparent
	Sprite 4 and 5		Colour Reg 24,25,26,27 = 3 colours + tranparent
	Sprite 6 and 7		Colour Reg 28,29,30,31 = 3 colours + tranparent
	Total          = 12 Colours + 4 transpaerents !!

	Each sprite has a maximum width of 16 pixels, unlimited height.
	Using all sprites this gives a maximum of 128 pixels wide.

	So I make the maximums to be a maximum of 12 colours and a maximum
	width of 128 pixels per scan line.

	If any of this info is wrong please let me know as I would like to be
	clear on this.

Cheers

SJR
