This extensive usage is a very good compatibility test for any emulator.

NLMSX has no limit on the VDP interrupt usage, and palette changes are
processed on the fly. So it should not be a problem. Except for some
overscan trick, if it is used.

NLMSX does have a line based VDP emulation which could cause a problem
when you are changing the palette colors on every line.

Are there some demos that use the same features ?
