So I'll have to try it with a 32 Pixel > sprite, or won't that make that big a difference? You would get more free cycles, but the general problems would still be there. For a 32 pixel output, you have to set the players to two copies close spacing, and the missiles would be set like that as well. Therefore it would be difficult to use them for anything. Also the timing would be similar, as you still have to change the player graphics during the display. Therefore all other things that you do during those scanlines will happen at a fixed number of cycles away from the graphics update. So if you change a colour right after the ship has been drawn, this change will happen after the ship has been drawn, no matter where on the screen the ship is. So if you wanted the colour change to happen for an object that is drawn on the left side of the screen, but the ship is drawn on the right side of the screen, the colour change will not happen in time.
