Well, there are the two tracker variants; full scrolling and moving
cursor + page flipping.
The full scrolling way was an obvious choice for the Amiga, as it had
hardware scrolling (no, not the blitter; changing the video read
pointer on the fly). It was actually easier to code than a moving
cursor row... But even on fast machines and video boards, that
requires some effort not to result in a completely useless
flickering CPU+video accelerator hog.
Page flipping OTOH, has to be handled in some clever way not to
become very confusing. Which way works best may depend on what the
display looks like, and of course, user preference...
