Play Super Famicom Controller Test Program (Japan) Online

Nintendo released the Super Nintendo Entertainment System in 1990, and with it came a small but practical piece of software known as the Super Famicom Controller Test Program. This utility was designed specifically for the Japanese market, offering a straightforward way for players to verify the functionality of their controllers without needing a full game cartridge.

You don't control a character; instead, you press buttons on the controller and observe the screen. Each input lights up a corresponding icon, allowing you to test the responsiveness of the directional pad, face buttons, and shoulder triggers. The objective is simple: identify any unresponsive or sticky buttons. The process is immediate and methodical, with no pacing or difficulty to speak of. It feels like running a quick diagnostic, a quiet moment of maintenance between gaming sessions.
