...still interesting thread, as I have the same problem with a file, I encrypted about 15 years ago.
I compiled the bfacs2hashcat.c and it seem to work fine with some test files I have encrypted right now with the old BfACS I still have.
But unfortunately using it with the old file (size about 200mb) I always get the message

'Short read while trying to read file header from xy.zip.bfa".

Any idea what that means or how to get the hash anyway? Thanks!
