I want info about 3DS homebrew apps to be easily available within the fediverse, so I wrote this guide.
Overview
Rehid is a homebrew app by Hax0Kartik that can semi-permanently remap buttons, the circle pad, and/or touchscreen taps for individual 3DS games.
Uses (non-exhaustive):
• Fixing an annoying control scheme
• Mapping older game’s camera controls to c-stick
• "Fixing" a broken home button
Installation:
- Download the latest release from Github or Universal Downloader
- Run the rehidhelper.3dsx file
- Select “download rehid”
- After it downloads, reboot your 3DS.
Using Rehid:
- Configure a remap using mikahjc’s remap builder
- Run rehidhelper.3dsx again
- Scan the generated QR code
- Select the game you want to apply it to.
- Profit
The remap will be in effect until you overwrite it or delete your game's titleid folder from the rehid folder at the root of your SD.
Tip(s) and Trick(s):
Tip: If you want a remap to apply to all titles, select the Blue G for Global at the very end of your software list.
Trick: You can find premade Rehid QR codes for some games online. Here's a compilation of a bunch on Github.
Troubleshooting:
For general questions, commenting here works.
For errors, best to refer to the comments on the creator's gbatemp post.
