Could you please post some source code then? No, in the end I optimised my original code. This sprite system is capable of free movement of the sprite around the screen, and does not use background graphics at all. I'll be delighted to post the source code to the list - but I would like to clean it up first. I'm just playing with colours now - the original RGB I chose were essentially random - now I'm using much closer colours - and it looks (to my eye, at least) slightly better. Current colour choice R = $32, G = $C6, B = $70 > Have fun! Its been a great challenge, hasn't it :) I'd just LOVE to see what some of the machine's designers think of the machine being pushed in this way. Would they be amazed?
