Proxy DLL
GenTool acts as a proxy between the game and DirectX, but can also chainload other custom proxy files. By default it will try to load a proxy dll in the working directory with the name
d3d8x.dll. Alternatively a proxy dll can be given a custom name and specified with the command line argument
-proxy YOUR.DLL.
A sample use case for this feature would be the use of a
DirectX 9 proxy.
