This function/subroutine covers from 7C59-7CA2.

These two points are actually a single function/subroutine, 6BDB-6C63.

So the question becomes, where do they take their parameters from, and 
what values have what result?  Once I figure that, I'll probably rewrite 
the functions based on the loader code I used in Qix and Pick-a-Dilly 
Pair.

A multi-file version *specifically* designed for ProDOS may take more 
space - of course the ProDOS kernel itself takes about 15K disk space, and 
more in later versions - but can be more readily run off 3.5" disks, hard 
disks, flash cards, etc., than if it's designed for DOS 3.3 and won't work 
under ProDOS.  Of course this pushes a lot of 48K games up to 64K.
