Hidden Game#

Watch on YouTubeHold B + Down on Controller II, then reset the console. After a while, both controllers on the screen will automatically pass all the checks and a mini-game similar to the toy game Simon will begin.

The program will flash a button for you to press on Controller I, and you must press it as quickly as possible. If you press the correct button in time, a sound will play; if you miss, a different sound will play. The game will then move to the next button. Your goal is to correctly press as many buttons as possible.

Source Code#

The source code for the mini-game is present at the end of the ROM. The source refers to the game as "Ura Asobi", which means something like "Hidden Game".
