I’m having trouble using JoyToKey from HyperSpin or RocketLauncher

In case you’re having difficulty using JoyToKey from some other launcher applications such as HyperSpin or RocketLauncher, please try to start JoyToKey directly as a standalone usage without those wrapper applications, and try to configure and understand JoyToKey by itself.

In other words,
1. Please unzip JoyToKey in some folder where you definitely have a write access (e.g. desktop or your documents folder)
2. Start JoyToKey by double-clicking “JoyToKey.exe”
3. Save registration key and/or make some update to a profile, and exit once
4. Start JoyToKey again and confirm that the registration key and profiles are properly saved

For more details, please refer to this post.

After confirming JoyToKey works by itself, please search some documents in Google for using JoyToKey with a specific launcher application. For example, this is a good page for HyperSpin, and that page emphasizes the importance of unmarking “read-only” flag on the top HyperSpin folder. (Just unmarking “read-only” flag on its subfolder “JoyToKey” won’t be good enough)

Unfortunately, the author of JoyToKey cannot support or guarantee the functionality when it’s used from some launcher/wrapper applications. However, you should be able to find some document or instruction from Google Search for popular use cases.

Forcibly specify the configuration folder outside of the launcher app

In case you can use JoyToKey standalone but cannot use it from other app due to some folder or permission issue, it may be one idea to forcibly specify the configuration folder, for example the same folder where you installed JoyToKey for its standalone usage.

By default, configuration files (JoyToKey.ini and profiles) are stored in the same folder as where “JoyToKey.exe” was installed. However, JoyToKey allows you to change it.

You can forcibly set the desired configuration folder in registry. However, please note that the direct edit of registry can be a potentially dangerous operation and it is only recommended for advanced users who understand what the following means, so please use it at your own risk.

  1. Run “regedit” program (Registry Editor)
  2. Create a key “HKEY_CURRENT_USER\Software\JoyToKey”
  3. Create a string value “IniFilePath=c:\Whatever\Path\JoyToKey.ini”
