User guide

Remap Buttons

You first need to create a rehid.json file with the remappings you want. The file will contain what buttons you want to remap.

Option 1:

• You can generate your rehid.json files using this site written by @mcaboosec.
• Once you have the file ready, run rehidhelper again.
• Select the Scan QR code option, then scan your QR.

Option 2:

• Alternatively, you can manually generate your rehid.json file using the step by step guide written by @MarioKartFan.
