Move EmuNAND

This is an add-on section for moving the contents of a previous EmuNAND to your new SysNAND CFW, then removing the old EmuNAND partition. Note that the terms EmuNAND and RedNAND refer to slightly different implementations of the same concept.

You MUST have already installed arm9loaderhax + Luma3DS to use this.

What you need

  • An existing EmuNAND
  • The latest release of GodMode9
  • The latest release of FBI

Instructions

Section I - Prep Work
  1. Power off your device
  2. Insert your SD card into your computer
  3. Copy GodMode9.bin from the GodMode9 .zip to the /luma/payloads/ folder on your SD card and rename GodMode9.bin in /luma/payloads/ to start_GodMode9.bin
  4. Reinsert your SD card into your device
Section II - Backup SysNAND DSiWare Saves
