Duck Hunt, in case you've been living under a rock or simply born yesterday, is a light gun shooter that was released for the Famicom in 1984 in Japan.
It was released in the US on the NES one year later, in 1985, and in 1987 in Europe. An arcade version of the game was also produced and distributed across several regions throughout the 80s. The goal of the game was to shoot moving targets on screen with the NES Zapper, with the player only having a limited number of bullets to do so.
If you shoot all the targets, you can advance to the next stage. Miss enough, however, and the Duck Hunt Dog will appear and laugh at your poor shooting skills.
Mahna Mahna produced the Commodore 64 version of the game for this year's Transmission64 3rd Edition event, but you can download the game now from the C64 Scene Database. Compared to the NES version, it only includes two modes, games A and B, which control the number of ducks onscreen. You can aim using a lightgun, joystick, or mouse in port 1.
You can also plug the joystick into port 2 to control the duck in game A. Here's a video of the game in action from YouTuber Saberman:
