i think i successfully decrypted resident evil 6 save game.
i am able to find my skill points with a hex editor.
however, modification seems to be more difficult.
every time after i make changes and re-encrypt the file, the game complains the save data is damaged..
i either encrypted it wrong.. or there is checksum / data verification that needs to be dealt with..
here's my question.. what's the difference between the "update" modes of pfdtool? how do i know which one to choose?
