Tools for Repacking

Atelier PAK Decrypt

• Utility to decrypt and unpack PAK files from the GUST engine.
• Note that some of the Koei Tecmo games that use the encrypted GUST engine contain Japanese filenames. In this case, you can't just run the games extracted. Other games such as Atelier Ryza 2 can be run extracted because all file paths and names in the archives are in English.
  
  Example Usage:
  

  a17_decrypt.exe <input pak file>
  
  a18_decrypt.exe <input pak file>

QuickBMS

• One of the most powerful tools anyone has made. This can be used for all kinds of purposes including extracting game archives, replacing data in archives with null bytes and decryption.
• You need the correct BMS script for the game in question to parse the game files.

TTGames BMS Script [Modified]

• Modified version of TTGames BMS script by Luigi Auriemma for compatibility with some LEGO games that the public script struggles with.
• You will still need a patched EXE to run the games in an extracted state. Older games do not need an EXE patch.
