How to test a fight stick
Connect your arcade stick or leverless hitbox via USB, open this page in your browser, press all 8 action buttons, and rotate the joystick through all 8 cardinal and diagonal directions.
The layout automatically mirrors traditional Japanese arcade panels (Vewlix and Noir layouts), highlighting buttons in real time and rendering an 8-way directional gate visualizer.
Testing simultaneous inputs
Press multiple action buttons together (such as LP+LK for throws or MP+MK for parries) to verify that your controller's PCB registers simultaneous inputs on the exact same frame.
Dropping inputs during EX special moves or V-Triggers is fatal in competitive fighting games. Our high-frequency polling monitor flags any delay or dropped button registration during multi-button actuations.
Checking individual button switches
Tap each Sanwa, Seimitsu, or Crown mechanical microswitch lightly and firmly to check for sticky plungers, missed clicks, or switch chatter.
Arcade microswitches endure heavy pounding. If a button requires excessive force to register or chatters multiple inputs from a single strike, the internal microswitch contact is oxidized or fatigued and should be replaced.
Testing directional inputs and SOCD
Test your leverless controller's Simultaneous Opposite Cardinal Direction (SOCD) cleaning behavior by pressing Left + Right or Up + Down simultaneously.
Tournament rules (such as Capcom Pro Tour guidelines) mandate specific SOCD cleaning modes: Left + Right must resolve to Neutral (no movement), and Up + Down must resolve to Neutral or Up Priority. Our SOCD validator checks tournament legality live.
Per-switch response time
Evaluate switch actuation consistency across all 8 buttons to verify uniform response latency across punches and kicks.
Variation in switch travel or loose internal wiring harnesses can introduce subtle input lag variations between buttons. Consistent latency ensures predictable combo execution.
Common fight stick faults
The most frequent fight stick failures are worn lever microswitches, sticky pushbuttons from beverage spills, loose quick-disconnect terminal pins, and faulty USB cable breakout boards.
Because fight sticks use standardized modular parts, repairing individual components is simple. Diagnosing the faulty switch on this page lets you service your stick before tournament matches.
Frequently Asked Questions
How do I test my arcade stick?
Connect it by USB and open this page in Chrome or Edge, then press each button and work through every direction. Inputs register live, including simultaneous presses.
Can I test simultaneous button presses?
Yes. Multiple concurrent inputs are shown together, which is how you confirm your stick registers combinations rather than dropping them.
How do I know if a microswitch is failing?
Watch for inconsistent registration or a button that needs a harder press than its neighbours. Response time varying between buttons is an early sign.
What is SOCD cleaning?
How a stick resolves simultaneous opposite directions â left plus right. Different sticks and tournaments handle it differently, and this page shows what yours reports.
Does this work with Hitbox-style controllers?
Yes. Leverless controllers present as standard input devices and every button is read the same way.
