C3PO is a Maphack that uses Mousepad's Engine except configures it using an interface. It also tells you more information about the monsters you face like Attack Rating, Defenses, and Resistances each creature has. It needs D2Loader to run (because its also a run manager).

When C3PO runs with the maphack loaded, it uploads a DLL called R2D2.dll to do the maphack stuff. If you load it without it, it doesnt inject R2D2.dll to the game, making it "legit" except you are using D2Loader. Most anti-hack bots dont pick up on C3PO because of this dll. Warden does.
