Disassembly is a big help to someone who's rusty or new at 65xx
programming, though, and I don't really think there's any way to comprehend
the process of screen drawing without seeing some production code.  Better
to use one of the commented ones or some of the contributed code (Nick's or
elsewhere) but even if it's just to step through the code with PCAE, you've
gotta do it a few times to get the hang of it.

Yeah, I started having to do that in my Ballblazer clone before I lost
track of it.
