Since I am the original owner of this, I do believe this came with my NES system if I remember correctly.
This is a nice combo since it is not the orange colored version of the gun.The Mario game also played as well as can be.
Comes with the original game manual and the black protective cover and game cartridge, with the light gun.
I have read, these old light zapper guns do not function using a newer LCD style TV, but DO work with the older tube screen type TV's
Light gun was externally cleaned and tested and worked very good.It has some scuff marks and scratches but looks ok.Not having played Duck Hunt for many years, it is surprising how accurate the gun is and too keep trying to beat your old score (fun).
No refund, it was tested and cleaned and played to my satisfaction and should give you no problems at all.
