Frequently Asked Questions

How do I test D-pad diagonal inputs (↖ ↗ ↙ ↘)?

Press two adjacent direction buttons on your D-pad simultaneously (e.g., Up + Right). The diagonal chip visualizer above will illuminate in green when the combination is recognized cleanly.

Why are D-pad diagonals important for fighting games?

In fighting games (Street Fighter, Tekken, Mortal Kombat), special moves and combos rely on quarter-circle and diagonal inputs. Missing diagonal registers cause dropped combos.

Does this test membrane D-pads and mechanical D-pads?

Yes! It tests standard silicone membrane D-pads (DualSense, DualShock 4) and tactile switch D-pads (Xbox Series X/S, Switch Pro).
