How to Test Your Controller

1. Connect: Plug in your controller via USB or pair it via Bluetooth.
2. Wake Up: Press any face button (A/X/Start) to activate the browser detection.
3. Visualize: Watch the on-screen diagram. It mirrors your inputs in real-time.
4. Check Drift: Rotate your analog sticks. If the red dot moves when you aren't touching the stick, you have Stick Drift.
5. Test Rumble: Click the "Test Vibration" button to check your haptic feedback motors.

What is Stick Drift?

Stick drift occurs when the potentiometer in your analog stick wears out or gets dirty, sending "movement" signals even when the stick is centered. Our tool features a Drift Visualizer that draws a red trail behind your stick movements, making it easy to spot jitters or phantom inputs.

Troubleshooting

Controller not showing up? ensure you are using a modern browser like Chrome, Edge, or Firefox. Try unplugging and replugging the device. On Windows, ensure the drivers are installed via Device Manager.
