You can find a demo of the map scrolling system described below in the src/sp1-multi-map folder or you can download the TAP file.

We can’t optimize what we can’t measure, so my first step at multiscrolling is to do some Proof of Concept routines and establish a code harness where I can run some accounting in the background, and run any routine I want while measuring its performance.

I finished one of my last posts “SP1 Scrolling: Updated Performance Review” saying that my next scrolling experiments would not be SP1 related.

Following Derek Fountain’s suggestion, I have prepared a video presentation on my previous SP1 Scrolling articles.

I have reconfigured all tests to use a 16x24-cell scrolling zone, which is a more realistic size for a scrolling game on the ZX.
