Rehid 3DS

Rehid is a HID module (which are responsible for user-input) rewrite with the aim of easier button remapping for the 3DS.

Features

Button remapping with the help of a json file.
IR module is patched automatically so ZL, ZR, Cpad Pro (Cnub) can also be remapped.
Different button remappings for different games.

You need to have the latest luma for this to work correctly.

Download the latest release of rehidhelper.3dsx.
Open homebrew launcher and run the 3dsx.
Click A on the Download Rehid option.
Restart your 3DS and remap the buttons using one of the methods below (then apply your remapping file to use).

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:

Option 2:

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

Some premade configs can be found here.

How to Remap 3DS Buttons - Rehid (Portuguese) (Planeta 3DS)

v3.0 2021/06/07

You can now use luma's input redirection with rehid.
- With this there is no real disadvantage of using rehid over stock hid.
Fix touch screen bounds.
- This was being caused as rehid did not respect touchscreen calibration.
You can now also do TOUCH>KEY binding.
Fix a bug where rehidhelper created folders with wrong titleid.
For people with broken home menu button, you can now remap your home button to a key combo.

v2.1 2021/05/12

Fixed the issue where gyros/motion controls did not work properly for some people.

v2.0 2021/05/07

Rehid now supports custom luma builds(plugin/3gx).
- The previous version crashed when using custom luma builds, this was fixed.
IR patches have been rewritten.
- CPad Pro/cnub can now be remapped using the JSON file.
- The previous IR patches were unstable and CPAD Pro/cnub did not work with some games. The patches were rewritten from ground up, correcting this behavior.
Rehid now also supports the following remappings:
- Keys > touchscreen.
- Keys > CPAD.
- DPAD > CPAD.
- CPAD > DPAD.
Accelerometer/Gyroscope has been implemented.
- This fixes multiple issues like games getting stuck and 3D being unstable.
Introduce Rehidhelper.
- Rehidhelper is a hb app which makes it easier to install rehid/generate remappings.
- You can now easily generate your remappings using this site written by @mikahjc and then scan the generated QR with the app instead of having to manually edit the json file.
