Creates a proxy dll which sits between the game and original dll

Dll Proxy Generator

This project creates a new dll which sits between a game and the original dll. This way you can intercept all dll calls.

Game -> Your proxy dll -> Original dll

Original by Kristoffer Blasiak (https://www.codeproject.com/Articles/1179147/ProxiFy-Automatic-Proxy-DLL-Generation) i modified his project so the output fits my needs.

Build

Open DllProxyGenerator.sln with Visual Studio and build it

Usage

Generate the proxy dll source

.\DllProxyGenerator.exe "path\to\your\dll"

Be careful which dlls you try to proxy. I tried public windows dlls like d3d9 or user32 which work great. Game specific dlls with mangled function names wont work. Except someone knows how to counter this problem.

Build the proxy dll

Create a new Visual Studio dll project. Copy the generated proxy files into your project.

Remove every other file like stdafx.h

Change the following settings.

• General > Project Defaults > Character Set = Use Multi-Byte Character Set
• C/C++ > Precompiled Headers > Precompiled Header = Not Using Precompiled Headers

Use the new dll

Copy your new proxy inside the game directory. Some games have a different load mechanism. Depending on which dll you generated it could be possible that the game does not load your dll first in which case the proxy doesn't work.
