Switch And Joy-Con Notes
Switch controllers can expose different browser mappings depending on OS, Bluetooth stack and driver.
Joy-Con drift is commonly a center-offset issue, so the stick drift sample and deadzone guidance are the most important checks on this page.
Switch Checks
Use the live input grid to confirm the actual button labels before exporting a report.
Switch Pro Mapping
Check browser button and axis labels.
Circularity
Inspect analog stick travel around the gate.
