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.

Installation

You need to have the latest Luma3DS for this to work correctly. Hold Select while Powering up your 3DS and enable game patching from the Luma 3DS menu.

Download the latest version from the release page, install rehidhelper using FBI and then use rehidhelper to install rehid.

If you've installed rehid previously, please delete the /luma/titles/0004013000001D02 and /luma/titles/0004013000003302 folder manually and then reinstall rehid using the new rehidhelper.

User guide

How to use

Run the app on 3DS, and select the "Download rehid" option.

Reboot your 3DS.

Generate your remappings using https://mikahjc.github.io/3dsRemapBuilder/config

Scan the generated remapping using the rehidhelper app.

Make your own remappings

The rehid.json file will contain what buttons you want to remap.

You can generate your rehid.json files using this site written by @mcaboosec. Once completed, run rehidhelper and choose the Scan QR code option.

Or you can manually generate your rehid.json file using this step by step guide written by @MarioKartFan. Then put the rehid.json file inside this folder.

rehid.json sample

You first need to create a rehid.json file with the remappings you want. For eg:-

{
    "keys":[
        {"get":"R", "press":"ZR"},
        {"get":"L", "press":"ZL"}
    ]
}

With the above, everytime you press ZR key, R key would be triggered,

and everytime you press ZL key, L key would be triggered.

It is also possible to do custom key combos, i.e.,

{
    "keys":[
        {"get":"R", "press":"X+Y"},
        {"get":"L+R", "press":"SELECT"}
    ]
}

Now everytime you press X+Y, R key would be triggered and on pressing SELECT button, both L and R would be triggered.

Possible Keys are:- A, B, X, Y, SELECT, START, ZL, ZR, L, R, LEFT, RIGHT, UP, DOWN, CRIGHT(CPAD), CLEFT(CPAD), CUP(CPAD), CDOWN(CPAD)

Premade mappings

Some premade configs can be found here.

Reset mapping

Delete the json file in the rehid folder, or disable game patching.
