He doesn't have any sprites as such I see, so the problem becomes a fair bit easier. To scroll in single multi-color pixels requires use of pre-rendered shifted pairs (as I did and I think is done in Cheese & Onion) or adjusting the actual character data in real-time like in mountain king below. If, as you say, he's only scrolling in 1/2 char increments, then that is fairly easy by just manipulating registers. If you have vertical scrolling then you need to re-render the static text characters to compensate for the vertical-scroll offset otherwise it judders as you scroll up and down (because $9001 is only latched during the VBI). ![]() You need to have a raster split as VicTragic says then change the screen to point somewhere else (I used zero page). ![]() Did a similar split on my Super Mario demo.
