Unreal Engine Signature Check Bypasser

A hook to bypass the signature check function in Unreal Engine-based games, enabling modding and custom pak/utoc/ucas loading for the games that uses *.sig files (or encryption) to verify the archives.

Installation

1. Download the latest release from the Release section.
2. Extract the zip on the Releases page into your game's Win64 directory (usually found in the [Project_Name]/Binaries/Win64 path).

Tip

I used dsound.dll to load the bypasser dll. You can use any other asi loader you want instead of dsound, just remove the dsound.dll and grab a x64 asi loader from here then paste it in the same folder as bypasser.

Tested Games

• Eriksholm: The Stolen Dream (NoobInCoding)

If you tested this hook on any games and it worked, just leave a comment in this issue and I will add its name in here.

If the bypasser didn't worked for you

• Use another loader like winmm.dll
• If the game are using Anti-Cheat (like EAC), use some method to bypass it and then launch the game in AntiCheat-free mode
• Even if AntiCheat is disabled and in single-player mode, some games still needs to be launched offline.
