Forcibly specify the configuration folder outside of the launcher app In case you have trouble saving a preference or license key, please refer to this post. For example, confirm that you can launch JoyToKey standalone, and create/edit profiles and make them working with your controller. In case you’re having difficulty using JoyToKey from some other launcher applications such as HyperSpin or RocketLauncher, firstly, please confirm whether JoyToKey as a standalone application works by itself, without using wrapper launchers.
