Button Masher (WarioWare: Touched!)
From the Super Mario Wiki, the Mario encyclopedia
This microgame can be seen on the reverse box art.
The objective of the game is to mash of the NES controller (Famicom controller in the Japanese version) to clear the game on screen. None of the games represent an actual NES title, but they are all inspired by games of the 8-bit era.
