Okay, so I got an NES, a Super Mario Bros/Duck Hunt cartridge and a flatscreen CRT TV (I repeat: it's a CRT TV). The first Zapper I used to play Duck Hunt didn't work. It did NOTHING AT ALL when I pulled the trigger: At the menu screen, I point the gun away from the TV to select the game mode and the cursor just stood still; it can't shoot the ducks in the game. I thought the gun was broken and get another one. This time, nothing changed ! The same exact thing happened with the second Zapper. Well, now I guess the problem is not the Zapper itself. Can somebody help me with this case?
