It seems like the RAM page stuff is where the confusion lies. It's noted in the
function docs that PSPR_NR requires RAM page 4. Can everything else run with page
4 active? Must it be reset before the program ends?
Meanwhile, I just tried setting the page at the very beginning, and not resetting
it. It's become more efficient, resetting my calc's memory without bothering to
crash. :-)

For the sake of brevity, I just included the sprite data immediately after the
routine (which at this stage is exactly the case in the unfinished source).
The reason I'm asking such a newbie question on the list is that I can't find my
answers in any documents. Either documentation is lacking for beginners, or it's
hidden very well. If I must learn through pain, I'll do so. :-)
