About this mod
This is a tool I made to peek inside the DLL files of the game to better assist me in modding the game.
Its not a direct mod for the game but may help those stuck modding trying to find a field or function within one or more of the core DLL files and even help make sure their own DLL files are compiling correctly, as mine werent.
