The time has finally come! The Hyper Blaster HD for Duck Hunt is compatible with NES. Insert your Duck Hunt for NES cartridge into the special Hyper Blaster HD Adapter, then pop it into your original toploader console or compatible toploader system (not compatible with the RetroN 5). Plug the Hyper Blaster HD light gun into the Player 2 port and a standard controller into the Player 1 port. Youre ready to hunt. Note: Currently, the Hyper Blaster HD is only compatible with Duck Hunt, specifically the 2-in-1 Super Mario Bros./Duck Hunt combination cartridge.
