About rehid
One way to set up remaps is mikahjc's 3dsRemapBuilder page. Make your mapping there, then pick Scan QR code in rehidhelper and scan it. You can also write a rehid.json by hand and put it in the rehid folder. Each rule pairs the button you press with the one the game sees, and combos work on both sides, so X+Y can give R, or Select can give L and R together.
For a different mapping in one game, make a folder inside rehid named after its title ID and put that game's rehid.json in it. The release also has an experimental build of the module.
Release notes
v5.0 · v5.0 Sixth Release · Apr 5, 2026
This is the sixth public release of rehid.
E: A hotfix has been made which fixes Zl/ZR behaviour on n3ds. Please update!
The following changes have been made:
- Fix a bug due to which ZL/ZR wouldn't respond after sleep.
- Fix a bug in turbofire due to which remapping weren't applied correctly.
- Fix bugs in title selection screen due to which mappings were generated for the wrong tid. (Sorry!)
- Other minor improvements.
One of the major features that have been worked for this release is Circle Pad Pro support on O3DS. This means you can now enjoy your Circle Pad Pro even with games which do not support it! However, this is highly experimental, and as such not included with the main release. Bugs and Crashes are to be expected and should be reported here on github or on my discord server: https://discord.gg/hyuvmb9.
Folks interested in this feature can download 0004013000001D02_experimental.cxi, rename it to 0004013000001D02.cxi, and put it in /luma/sysmodules folder. Don't forget to enable Load external firms and modules from luma config menu!
I would like to thank @rosaage, @EthanMac1915, @Mayonaka-7 and @tittilvero who have spent countless hours helping me test the cpp feature.
