Item #: SCP-XXXX

Object Class: Euclid

Special Containment Procedures: A Foundation-operated bot ("I/O-SAURON") is to monitor SCP-XXXX for activity, logging all comments and uploaded videos to a secure server for later review. Once logged and recorded, online information regarding SCP-XXXX is to be expunged from external networks. All non-Foundation personnel aware of SCP-XXXX are to be apprehended, interrogated, and amnesticized.

Five NES1 consoles modified to run SCP-XXXX-A instances are to be kept for testing purposes. All SP-XXXX-A instances are to be clearly labeled and stored in a secure locker on-site. Access to this locker is limited to Level-3 personnel.


SCP-XXXX is Haunted, an unlicensed platform adventure game developed for the Nintendo Entertainment System. Published independently in 1988, the game was notable for its limited release (three hundred copies) and unique method for bypassing the North American version of the 10NES lock-out system.

Each cartridge includes two transistors that function as a voltage inverter. When activated, this component produces a negative-charged voltage spike that can temporarily disable early versions of the console's CIC (Checking Integrated Circuit), bypassing the authentication lock and allowing unlicensed cartridges to run. Later iterations of the NES would add a series of 1k resistors along with diodes and grounds to prevent this technique from circumventing the lock-out unit. As a consequence, Haunted can only run on original or modified NES consoles.
