Ive got other plans for this as well anyway :D and not all are screen based ;) more soon on that though

I appreciate the challenge in making extreme compression work on SAM, but you need to achieve some significant compression benifits to make up for that extra space which could have been used for slightly-less-compressed data. :-) Well not exactly, because the decompression takes place once a level, after which you can reuse the space. If you can squeeze it into 24k then that's just the screen RAM. Like you though I'm dubious that you'd achieve much better compression than a fairly basic RLE algorithm, especially on the kind of graphics you want as background in a game (lots of large blocks of black and quite a few horizontal lines, usually). Happy to be proved wrong, of course :) Geoff
