Super NES Super Scope 6
The player is instructed to shoot the "bull's-eye" of the target. Doing so tells the SNES where the center of the screen is relative to the Super Scope and its interface box. After calibration, the player is asked to test the aim to verify its accuracy. It is not required to shoot the bullseye this time, but it's important that the shot mark lines up with where the player aimed and fired though.
