ZZZ-Hdiff Patcher: a tool for manually updating ZZZ properly

If you update the game by simply copying all the update files and then replacing them in the game client directory, that's actually not the correct way. You should merge the .pck.hdiff update with the old .pck file and delete the obsolete files listed in deletefiles.txt.

How to use?

For example, you want to update the game from 2.0.0 to 2.1.0:

1. Put the following files in the same place as ZenlessZoneZero.exe:

   • AudioPatch_2.0.0-2.1.0.txt
   • Cleanup_2.0.0-2.1.0.txt
   • hpatchz.exe
   • 7z.exe
   • Start.bat
   • game_2.0.0-2.1.0_hdiff.zip
   • audio_en-us_2.0.0-2.1.0_hdiff.zip

2. Run Start.bat and wait until the process finishes.

3. Now, your game is updated!

• Overview of the merging process:

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