The software works by intercepting inputs from a physical controller and translating them into a format that the game engine recognizes as coming from a legitimate Xbox 360 device. This is achieved through the use of Dynamic Link Libraries (DLLs)—specifically xinput1_3.dll or xinput9_1_0.dll —which are placed into the game’s directory. The "self protection failed error code 4" typically

However, conflicts arose between the legacy DirectInput methods used by older controllers and the modern XInput standards simulated by ViGEm. When the software tried to bind the virtual controller to the physical device, the memory address space collision triggered the self-protection mechanism, resulting in Error Code 4.
