The .load() process will slow things down somewhat, and I think that .draw()
will force a total redraw of the frame. This is probably where a good chunk of
the slowness is coming from.
How many different kinds of tiles are there? If each is saved as an individual
.bin or .ans, you might try combining them all into a single spritesheet. Load
the entire spritesheet into each 16x16 frame, then scroll the frame to
different x/y offsets as needed to reveal the desired portion of the larger
graphic. This would cut out the .load() and .draw() calls, as .cycle() (which
I assume is being called regularly on the overall parent frame) should take
care of redrawing all child frames as needed.
