Hiii! I'm Yagi, and I'd like to introduce XC24 Diagnostics, a diagnostic tool for Windows that lets you test your mouse, gamepad/controller, and headset — no internet connection or account required. It detects common issues like phantom double-clicks, misaligned joysticks, or buttons that don't respond, with interactive visual tests. It's compatible with PlayStation and Xbox controllers, and the interface is available in Spanish, English, Russian, and Japanese.

It's free, but if you find it useful, you can leave an optional donation ☕
