Description: SCP-XXXX is Haunted, an unlicensed platform adventure game developed for the Nintendo Entertainment System. Published independently in 1988 by June Richardson, 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.
