I bought this item to take the security bit off of my SNES games so I could get in them and check them out and it worked great! It did it's job wonderfully! I also was able to open my old Gameboy games. I haven't tried it on an NES game yet, but if you need a bit to get into an SNES/Gameboy game and want a good deal, than I recommend this Lukie Bit!
