Reple

!thank you so much !you save me

Hello, I'm recently trying to extract 'Riddle Joker', Yuzusoft, for my fan translation team It's made with Kirikiri Engine, and I used all of kirikiri unpacking tool, but it just resulted random data files. I think the company set private encryption to xp3 files. To decrypt this, Where can I start? I can use python and c++, and have little understanding in reversing and data tree Thank you.
