Hi all, From my understanding the 7800 processes graphics on a line by line bases. So you're only limited in the amount of sprites per line by how long it takes you to draw them. I've done this (sort of) on the A8 with different ANTIC modes (such as ANTIC E and ANTIC F) but it's still going to take some getting use to. I've also dealt with display lists in the A8 for so long that I still can't get a grasp on to the 7800 concept. Anyone know of a way that would help me understand it better? A number of you come from the A8 environment. Did any of you have trouble getting this? If so, how did you overcome it? Take care, Dennis
