You are correct. I have the Cybergadget Save Editor and thus I know how the data should look like in plain text. The output of Savedatafiler is definitely not correct.
I remember that for some time when the original Monster Hunter 4 released, Cybergadget also had trouble to offer correct decrypted saves of the game so I assume Capcom added an additional layer of encryption to protect the online multiplayer from cheaters (well, without success obviously).
I attached a Savedatafiler output and a clear text output if somebody wants to take a look. Please note that these are not corresponding files, SDF output does not contain the same data as the cybergadget output. Just for structure viewing purposes.
