This reminds me:  Has anyone tried decoding the "Final Fantasy VII"
memory card save files?

I'd really like to mess arouns with them (giving me extra money and
experience, all the coolest items, etc.)

I tried "save", run the game for 1 second, "save" again, to compare
the files, expecting to see one location change by "1" (the time
value.)  BUT: they are *radically* different.  Like 128 bytes or more
are different.  How much "save" data could really change in 1 game
second?  Sheesh!

And to make it worse, it seems to have a CRC or checksum or something,
because when I tweak the locations that I think are Gil (money) for
example, my expected value shows up in the game "load from file" screen,
but it won't load the tweaked save file, complaining about "bad or
corrupt save file" or something like that.

Anyone from Squaresoft reading these Yaroze goups?  Maybe you'd like
to give a fan a hand?  :-)

Anyone?  Any ideas?
