Oops, my fault. Anyway, that should make your kernel quite simple.

Depends on the structure of your kernel. Free repositioning of multiple
objects inside the kernel is quite tricky and usually requires some
compromises.

You *can* use the scanline counter for the sprites too, though that makes
the code a bit more complicated. When you find my skipDraw descriptions you
