if __name__ == "__main__": # Example usage unpack_cri('input.cri') # Assume you modified output.bin pack_cri(open('output.bin', 'rb').read(), 'output.cri') Test your tool on a few files to ensure it works. Refine it based on feedback and for handling different scenarios. Conclusion Creating a tool like the "PES 2017 Cri Packed File Maker" involves understanding the game's file formats and designing a simple application to automate packing and unpacking tasks. Always ensure you have the right to modify game files, and respect the intellectual property of game developers.
