Switch SD to NSP Dumper (SwitchSDTool) 1.10

1 Screenshot

This is a tool used to dump NSP files from the games/dlc/updates you legitimately obtained from the e-shop.

This is done through obtaining a nand backup via hekate, the required console specific keys via biskeydump from your switch, along with other keys via kezplez needed for hactool. It also requires googling for eticket_rsa_kek.

For minimal ban risk, Delete your wifi connection profiles, put your switch into airplane mode, BACKUP YOUR NAND, run biskeydump, follow the instructions for running kezplez to get keys.txt, RESTORE YOUR NAND.

At the end of this, you will then need hac disk mount to dump PRODINFO.bin, and mount the SYSTEM partition.

How to dump NSPs from your SD card for the First time

  1. Step 1: Put your Switch into Airplane mode and remove ALL wifi connection profiles. (Safety measure to avoid a potential ban.)
  2. Step 2: Follow the tutorial at https://gbatemp.net/threads/backup-restore-your-nand-get-your-biskeys-tseckeys-keys-txt-guide.513386/ to dump your nand, keys.txt and biskey dump.
  3. Step 3: Restore the nand back up, if you have not already done so via above tutorial following the dumping of biskey.txt and keys.txt. (Safety measure to avoid a potential ban.)
  4. Step 4: Grab Hac Disk Mount.
  5. Step 5: Power off your switch. Mount the SD card from your switch to your PC.
  6. Step 6: Open up hac disk mount with Administrator Priveleges. (This is mandatory in order to install the Virtual Drive driver.).
  7. Step 7: Open up rawnand.bin in hac disk mount.
  8. Step 8: Double click on PRODINFO
  9. Step 9: Open up biskey.txt and copy in the Crypto and Tweak keys from Bis Key 0, then click on Test. Make sure the result says Entropy OK.
