single-byte flip in ScummVM game data

[Alexandre Detiste]

Hi,

I've found another game with a version with a single-byte flip...

Why does this happen, is this some kind of stenographic mark ?

A bitmask that enable censorhip ?

Here it is even more dubbious, because this is the only file that
has it's name in lowercase in the archive.

I see you dig.la1 has exactly the same size as the one in
the packages sold by GOG.com; maybe this in another one-bit-flip ?

Would you want to compare the two files ?

dig.la1.xz is 39M, I can provide you this
file's url on my server in a private mail.
(it's on a tmpfs, will remain till my holidays)
