-This is a pseudo-driver module that intends to improve compatibility and stability in games using Direct3D 8 for rendering by converting all API calls and lowlevel shaders to equivalent Direct3D 9 ones. By that it also opens those games to the new possibilities from proven tools and wrappers written for Direct3D 9.

-You'll need Visual Studio 2013 or higher to open the project file. It is recommended to install the old standalone DirectX end-user runtime, which is required for the D3DX libraries used for disassembling and assembling the shaders.
