I might not exactly be the name you think of when it comes to ProDOS filecracking. I've done a bunch though.
Generally, I've tended to stick to single-load stuff, or stuff where
finding the patch points is not difficult. And when I've run into difficulties, I've often found hints in places like Computist.
While fighting with a few games that are giving me grief, I got to
thinking about one particular one: "Ae". This one takes two disk sides,
and so it's a different challenge. My first thought was to try putting
the unprotected back of the disk into a disk image (this only works
because of sparse files). Then I want to try to do something like how AppleWorks allows itself to run either from two sides of a floppy, or a high-capacity storage media; this might be the way to get Ae to work from
a floppy under ProDOS-8! But the location of the disk code, on the text screen and page BF, is giving me grief.
My attempt to reconstruct Zenith from a postmortem hasn't been working,
but I do think I got Neptune to work.
For Mr. Cool, I just neutered out the high score save.
