My aborted Ballblazer-like demo is already capable of independently
scrolling two playfields horizontally and vertically, though it remains to
be seen if I would have gotten the rest of the logic in there before
running out of cycles. The grunt work in such a game would actually be
outside the display kernel, I think.

Yeah, my playfields (like Vanguard) were totally repetitive and didn't even
involve rewriting in the middle of the screen. That would be an issue with
a more interesting horizontal scroller.
