USB Gecko Box
USB Gecko is a cheat device for the Wii that is similar to the Action Replay. The USB Gecko's effects have been chronicled throughout videos and pictures alike, and has thus become popular. However, playing as an unplayable character or playing on an unplayable stage makes the game freeze. This is one of few differences between it and the Action Replay.
