I know that the Nintendo Zapper for NES is for Duckhunt but besides that what games can you use it with. Any?

Hogan's Alleys... Operation Wolf... there's others that I can't think of.

The Adventures of Bayou Billy (some levels)
Baby Boomer
Barker Bill's Trick Shooting
Chiller
Freedom Force
Gotcha! The Sport
Gumshoe
Hogan's Alley
Laser Invasion
Lone Ranger
Mechanized Attack
Operation Wolf
Shooting Range
To the Earth
Track & Field II (bonus event)
Wild Gunman

Chiller is sweet since its the only game (to my knowledge) that allows 2 Zappers to be Hooked up. I've had the pleasure of playing this game, and in truth it's better than most other zapper games as far as I'm concerned. Nothing more fun than shooting a body into the waiting mouth of an 8-bit alligator. Ah, good times...
