Hourglass9 is a noob friendly, safe, arm9loaderhax/sighax only NAND dumper & restorer for the 3DS console. All the functionality found within it is in Decrypt9, too, and possibly was in Decrypt9 for ages. What new it brings to the table is simplicity and (even more) safety.

Arm9loaderhax is a prequisite for this, and with it, it is impossible to brick your console with Hourglass9.

Note: While the stuff written above should be enough for the average user, advanced users will still need to use Decrypt9 for more specific modifications of their console OS. Also keep in mind that you alone or responsible for keeping your backups safe and not losing them.


  • Dump your SysNAND/EmuNAND - Make backup copies you can later return to.
  • Restore your SysNAND/EmuNAND - This will never overwrite your existing arm9loaderhax installation.
  • Validate existing NAND dumps - Make sure they are ready to restore.
  • Dump & Inject the Health and Safety app - Setup a CIA installer in your system. More info.
  • Dump retail game cartridges to .3DS/.CIA/.NDS.
  • A nice dragon logo on the bottom screen.
