GodMode9 is a full access file browser for the Nintendo 3DS console, giving you access to your SD card, the FAT partitions inside your SysNAND and EmuNAND, and basically anything else. Among other functionality, you can copy, delete, rename files, and create folders.

  • GodMode9’s restore feature will allow you to restore your entire 3DS internal storage using a previously created backup file. Restoring from a SysNAND backup should be reserved as a last resort and a less drastic solution is likely to be possible unless your 3DS is completely inoperable (bricked).
  • Use GodMode9 to convert your.3ds ROM’s to.cia files that can be installed on your 3DS; Dump Cartridges to SD. Yes, you can convert 3DS files from iPhone, iPad and other mobile devices, because AnyConv 3DS Converter is a multi-platform web service. That fake CIA will boot your slot-1 flashcart.

Note that if you have any payload files other than GodMode9.firm in the /luma/payloads/ folder on your SD card, holding (Start) on boot will display a “chainloader menu” where you will have to use the D-Pad and the (A) button to select “GodMode9” for these instructions.

GodMode9 is powerful software that has the capability to modify essentially anything on your console. Though many of these modifications are locked behind a permissions system, and it is impossible to accidentally perform dangerous actions without deliberately unlocking permissions, you should still follow instructions carefully and keep backups just in case.

Im using godmode9 v.1.4.3 and it still does not work. I added in the aeskeydb.bin, as well as seeddb.bin and enctitlekeys.bin. The.3ds file does not appear to be broken, since it can run on Citra. However, I downloaded a different.3ds rom (not a rom hack) and it is building the.cia just fine. Using Godmode9 to dump or backup your legit titles & games from your Nintendo 3DS on Luma CFW. Backup your eShop Games to an Installable CIA file!- Intro Vid.

How To Install Godmode9 3ds

This is add-on section for region changing your CFW SysNAND. This is done by installing the 11.5.0 CTRTransfer image for the region you want to switch to.

Note that region changing is almost completely unnecessary since Luma3DS supports out-of-region games and individual title Locale Emulation. Additionally, running NDS games with alternative out-of-region languages is supported by TWiLightMenu++.

To use the magnet links on this page, you will need a torrent client like Deluge.

Note that if you have any payload files other than GodMode9.firm in the /luma/payloads/ folder on your SD card, holding (Start) on boot will display a “chainloader menu” where you will have to use the D-Pad and the (A) button to select “GodMode9” for these instructions.

This process will unlink your NNID from the system, since it will no longer be compatible with it. NNID’s are locked to the region of your device that created them and cannot be transferred between regions without a very complex and advanced process.

Convert

After this process, you will not be able to access the eShop. This includes any feature that uses an NNID, such as game updates, purchasing DLC, or online play in certain games. Region changing to your original region will usually not fix this issue.

Note that occasionally the eShop will inexplicably still not work for devices that it should work for. This is entirely to do with Nintendo’s servers, and I really do not have any control over it. Additionally, note that occasionally the eShop will inexplicably work for devices that it should not (such as some New 3DSs). The cause for this is currently unknown.

Region changing using CTRTransfer (which this method uses) seems to cause reboot patches to break. The cause for this is unknown, but Old 3DS users, for now, will be unable to play extended memory mode games (such as Monster Hunter, Super Smash Bros, and Pokémon Sun / Moon) until they format their devices.

You MUST have already installed Luma3DS and boot9strap to use this. Survive in space download for mac.

What You Need

  • The v1.9.2pre1 release of GodMode9
  • The latest release of FBI(the.3dsx file)

    • - New 3DS or 2DS - 11.5.0 - KOR - CTRTransfer
    • - New 3DS or 2DS - 11.5.0 - USA - CTRTransfer~
    • - Old 3DS or 2DS - 11.5.0 - EUR - CTRTransfer

    • - Old 3DS or 2DS - 11.5.0 - USA - CTRTransfer
