Gamepad guides — tests, problems and troubleshooting
ACC64 guide hub for stick drift, deadzone, input lag, buttons, triggers and connection. Start with the online tester, then choose the guide that matches the symptom.
This hub brings the online tester and focused troubleshooting guides into one place. Start by reproducing the behaviour in a neutral test, then open the article that matches the symptom. That makes it easier to separate a hardware fault from an operating-system, connection or application issue.
Start with the online tester
The tester gives you a quick baseline without installing extra software. Check the main inputs, note the symptom, and only then start changing settings.

Frequently asked questions
Which guide should I start with?
If you do not know the cause, start with the online tester. Once the symptom is confirmed, choose the guide focused on that behaviour.
Does a browser test replace professional diagnostics?
No. It helps narrow down the problem and compare device behaviour, but it cannot confirm every electrical or mechanical fault.
Should I test on another computer?
Yes. When the result is unclear, a second computer or another browser helps separate a device problem from a system configuration issue.
