Using tiles is no use to me as they are intricate and all very different -- all I need do is compress the black areas. I think 70k each is pretty good for such such a simple algorithm. The virtual screen is free as it is on the frame buffer (which I don't need for textures etc). This makes 2-player split-screens very easy.

(not even PAL users seem to care which is strange, your losing 16 whole scanlines!) Laters, Jim PS I have to say the manual is EXTREMELY clear regarding making a VAB file.
