Steam API Check Bypass

Bypasses Steam API dll integrity/size check by hooking CreateFile API.

Build

• Build with Visual Studio 2022.

Usage

Method 1

• Use CFF Explorer and add SteamAPICheckBypass dll import to game main exe, then put the SteamAPICheckBypass(x32).dll dll beside game exe.

Method 2 (VersionShim) (x64 for pre-built version.dll)

• Put SteamAPICheckBypass.dll version.dll libraries.txt beside game exe.

Configuration (Optional)

• Create SteamAPICheckBypass.ini and write file names you want to replace. Example:

[Replace]
OriginalFileFile=ReplaceFileName
steam_api64.dll=steam_api64.dll.bak
steam_api.dll=steam_api.dll.bak

[AfterFirstTime]
OriginalFileFile=0
steam_api.dll=0

• Replace: The file name to replace.
• AfterFirstTime: Start to replace after the first read of the file.

Internal Process

1. The Crack will check useinternallist in the source code, if it's true, it will use internalreplaceList.

2. The Crack will try to parse the ini file and add them into the replace list.

3. If ini file not exist, try find steam_api(64).dll.bak, steam_api(64).org,steam_api(64)_o.dll and add the existed file into replace list.
