Help: Issues unpacking and packing Ready or Not .PAKs using QuickBMS (UE4/UE5)

Hello Folks,

I've been using this quickbms script to extract a .ini file and reinject it back to the original pak, the batch file are as follows.

Extract.bat

---

set curr=%~dp0

"%curr%..\quickbms_4gb_files.exe"  -f "*/AILevelData.ini" "%curr%ron.bms" "%curr%pakchunk0-Windows.pak" "%curr%sources"

pause

Repack.bat

---

set curr=%~dp0

"%curr%..\quickbms_4gb_files.exe" -r -w "%curr%ron.bms" "%curr%pakchunk0-Windows.pak" "%curr%sources"

:: enable line below to automatically copy modified pak file (adjust target directory first)
::copy "%curr%pakchunk0-WindowsNoEditor_0_P.pak" "C:\Games\SteamLibrary\steamapps\common\Ready Or Not\ReadyOrNot\Content\Paks" /Y

pause

 

The script worked fine ever since the early access stage of the game until the game changed from UE4 to UE5 in this July.

The script can unpack the .ini file normally but fails to pack it again, even if I tried to pack it directly after unpacking it ran into this error:

  offset           filesize   filename
--------------------------------------
< 0000000000000000 0          ReadyOrNot\Config\AILevelData.ini

Error: file "ReadyOrNot\Config\AILevelData.ini"
       the reimport option acts as a reinjector, therefore you cannot insert a
       file if it's larger than the original for not overwriting the rest of
       the archive which cannot be loaded correctly:

         new size: 8834 (35281 uncompressed)
         old size: 7038 (35281 uncompressed)

So far I've also tried repak as well as the official UnrealPak but none of them seemed to work, as they both will result in a different pak size after repacking.

Any assistance is highly appreciated.
