Why Mapping Can Differ
Browsers, operating systems and drivers can expose the same controller with different button labels or axis order, especially for Switch, generic and specialty controllers.
The mapping page helps you document what the browser sees before changing game settings, emulator bindings or repair notes.
Mapping Checks To Run
Work through buttons, axes and D-pad directions one at a time so mismatches are easy to record.
Axes And Triggers
Move sticks and pull triggers slowly to identify analog ranges.
D-pad And System Buttons
Check directional and menu buttons that often map differently.
