The Aladdin Deck Enhancer is a cartridge based system that allows software on Compact Cartridges to be played on the Nintendo Entertainment System. It is similar to the Datach system for the Famicom, but without the Barcode feature. Invented by Richard Darling, the Aladdin Deck Enhancer contains a bypass Security Circuit Chip, a Memory Control Chip, and a Graphics Chip:side B which would work with the lock-out chip and other features inside the Nintendo Entertainment System. First the Compact Cartridge would be inserted into the Aladdin Deck Enhancer, which is shaped the same as a standard NES cartridge, and then this would be inserted into the Control Deck. Inside the slot where the Compact Cartridge is placed is a recessed switch, which changes the Security/Region settings from position A to position B.
