The modular switch custom firmware


Put ReiNX folder on the root of your switch's SD card and run ReiNX.bin with your favorite fusee launcher.


You'll need devkitpro with devkitARM (along with the devkitarm-rules package) and run:

git clone --recurse-submodules
cd ReiNX && make

To compile with Docker, chmod +x and run the shell script ./ After that, just check out dir. This will compile without requiring installation of DevKit* dependencies.


  • Modularity (doesn't rely on or require any SD files to run; customize SD files to your liking)

  • Loads all KIPs from /ReiNX/sysmodules/ directory

  • Optional custom kernel/secmon/warmboot

  • FS patches on the fly (NCA verify/cmac and optional nogc)

  • Kernel patches on the fly (optional debug mode)

  • Exclusive ReiNX sysmodules

  • ES patch in RXP patch format (used with custom loader.kip)
