*sigh*

The demo was showing the colour sprite system capabilities.  I am presenting sample images to show how the >>colour<< and interleaved interlacing works.  Telling me that the images aren't the right aspect ratio, or that images should be cropped, *is* ENTIRELY missing the point. What I said earlier was that images can be any aspect ratio I want them to be... and they can - and are.  I just happened to use the full width/height of the sprite for the example(s), and thus they were stretched.

See ---> I don't *CARE* what aspect ratio these sample images are.  I'm only interested in showing that the COLOURS and interleaving / interlacing are working nicely.  You say the images are stretched?  I agree. They're the wrong aspect ratio?  Absolutely.  But we already knew that.

Stretching/squashing/manipulating an image to any desired aspect ratio is a piece of cake - a trivial preprocessing of the image.  Displaying coloured sprites on a '2600 is *not* a piece of cake.  I was hoping people would look at the underlying technology and understand what it represented.  

Cheers
