The Goldberg emulator replaces these original Steam DLLs with its own version to trick the game into thinking Steam is running.
If you are trying to get this specific version running, follow these general steps based on standard Goldberg emulator installations:
: You can often change your in-game name by editing account_name.txt found in the emulator's settings folder (typically located in %appdata%/Goldberg SteamEmu Saves/settings ).
: Unzip the contents of the .zip file into a dedicated folder on your computer.
: Do not launch the game through Steam. Run the Madness Project Nexus.exe directly from the folder you extracted.
