my first version of the emuNAND Tool is finished.
Thank you to all my beta testers! (5rg, AgoraphobicNosebleed, DAHU75, Gildoniel, hashcheck1, mvmiranda)


About the tool:
This tool can be used to extract the NAND file from a emuNAND SD card and to inject a NAND file into the emuNAND SD card.
The extracted NAND file is a fully working 3DS NAND file and is also flashable to the 3DS.
If you want to flash the emuNAND to your 3DS, you will need to do a hardware modification. (nand flash dump (3ds xl) / NAND Flash Dump (3DS))
This is NOT needed if you only want to backup/modify your emuNAND.

Supported emuNANDs: Gateway and clones like R4i Gold 3DS Deluxe Edition, 3DS Link, Orange 3DS, MT Card

The emuNAND SD gets detected automatically!
To inject a NAND file, the SD card has to already contain an emuNAND partition.

What is NOT possible?
This tool does not enable you to magically use the Gateway (and clones) on a non 4.x system version.
You can't inject games.
You can't flash the Gateway mode to the 3DS.
You can't modify the firmware (no region bypass, backups,...).
You can't extract any keys.
You can't downgrade your 3DS with this tool. It only modifies the emuNAND on your SD card.
You can't use a NAND from another 3DS on your 3DS.



Usage examples:
  • You updated your emuNAND to a version which is not supported by the Gateway (or clone) and want to go back to an old version.
=> Extract the emuNAND each time you update it. You can then switch the emuNAND version by injecting the backup.

  • Your emuNAND is on the latest version, but the Gateway (or clone) does not support the eshop of this system version yet, but you want to buy a game.
=> Backup your 4.X 3DS NAND, extract emuNAND from SD, flash extracted emuNAND to 3DS, open the eshop and buy a game, backup the 3DS NAND, flash your 4.X NAND back onto the 3DS, inject the new 3DS NAND backup (with the downloaded game) into the emuNAND SD.
(ATTENTION: make sure you have a valid 4.X NAND backup and are able to flash it back with a hardware mod!)
  • You updated your emuNAND to a version which is not supported by the Gateway (or clone) and want to go back to an old version. But you don't have a backup.
=> Backup your 4.X 3DS NAND, update your 3DS NAND by using a game cartridge, create a backup of the 3DS NAND, flash your 4.X NAND backup back to the 3DS and inject the updated NAND backup to the emuNAND SD.
(ATTENTION: make sure you have a valid 4.X NAND backup and are able to flash it back with a hardware mod!)
  • You want to do a system transfer, but the emuNAND does not support that. (System transfer is now possible in emuNAND)
=> Backup your 4.X 3DS NAND, update your target system to the latest system version. Do the system transfer. Backup the target 3DS NAND, flash the 4.X backup NAND back to the target 3DS, inject the NAND backup (after the system transfer) to the emuNAND SD.
(ATTENTION: make sure you have a valid 4.X NAND backup and are able to flash it back witha hardware mod!)
