XTool is program made specifically repackaging games by providing a full suite of useful features such as data precompression, archiving, encryption and etc. With that being said, nothing restricts it from being used on everyday files such as documents, pictures and media but with few limitations.

Read the documentation to find out how it works and how to use it.

Unreal Engine

Supported games

  • lzna compressed unreal engine 3 games
  • Encrypted unreal engine 4 games

Methods available

  • ue3
  • ue4

UE3

Usage
Place (unreal.dll) near xtool.exe and use -mue3

Notes
Only lzna compressed games are supported, mainly Mortal Kombat 11

UE4

m = method (1 = games that use borderlands3, street figher v... format, 2 = games that use rune ii format)
k = key in hexadecimal.

Usage
Place (unreal.dll) near xtool.exe and use -mue4:m1:kAAF9AF1F40225A1241C120533277804B09A56CE78CBF100C131423788DB0E34F

Notes

  • The library is required both encoding and decoding.
  • This tool only decrypts like ue4dt but since xtool also does precompress data so if a game for example is zlib compressed and also encrypted. You can use -mzlib+ue4:m1:kAAF9AF1F40225A1241C120533277804B09A56CE78 CBF100C131423788DB0E34F
  • The order of the method does not matter, you can write it as -mzlib+ue4:m1:kAAF9A.. (or) mue4:m1:kAAF9A...+zlib, it will still work.
  • The game will be decrypted and precompressed in one go but you have to use -d1 parameter

Example

[External compressor:xtool]
header    = 0
packcmd   = xtool.exe precomp -mzlib+ue4:m1:kAAF9AF1F40225A1241C120533277804B09A56CE78CBF100C131423788DB0E34F -c32mb -t100p -d1 --dbase - - <stdin> <stdout>
unpackcmd = xtool.exe decode -t100p - - <stdin> <stdout>
