Hoyo-Hdiff-Patcher: a tool for manually updating Hoyo Games properly

Copying the update files directly into the game folder is not the correct update method. You must merge the .pck.hdiff files with the original .pck files and remove the outdated files listed in deletefiles.txt. You can perform this process using the following tool.

Requirements

• Install python

How to use

1. Place the following files in the same folder as exe game:

   • 7z.exe
   • hpatchz.exe
   • patch.py
   • run.bat

2. Click run.bat and wait until the process finishes.

3. Now, your game is updated!

• The overview of merging process:

  Banks0.pck (59.5 MB)        // before update
  + Banks0.pck.hdiff (3.0 MB) // hdiff update
  -----------------------------
  = Banks0.pck (62.5 MB)      // new size after update
