Tool for encrypting/decrypting Yakauza Kiwami 2 saves.
Original decryption code from here by simontime. I added proper checksum calculation and split the tool into two executables for easier usage.
yk2_decrypt.exe data.sav will output into data.json.
yk2_encrypt.exe data.json will output into data.sav.
Alternatively you can just drag and drop the file onto the respective exe.
