I have actually tested using 1, 2, 3, 4, 5 and 6 bit planes. The difference in speed is only in the horizontal line draw code and is pretty much exactly proportional to number of planes. There’s no dramatic difference between 5 and 6 planes, which I thought there would be. I don’t know if this is because I’ve got some fast memory, so the only access the CPU needs to chip memory is the actual drawing.
I should probably test with 6 planes being displayed but only drawing the ball to the first 3, and without fastmem.
