Gust Tools
  • Various tools for modding of Gust engine games (think Koei Tecmo).
  • You will be particularly interested in gust_pak.exe because it can extract ecnrypted Koei Tecmo PAK archives leaving a JSON file and decrypted files. You can then use gust_pak.exe to rebuild the archive from the JSON file. They are so similar you can XDelta the new file to make it the old file and have a 100% CRC perfect repack. The delta files are only a few kb in size, so I didn't even bother using HDiffZ in this case. It's not worth the long patch generation time.
