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

Note from developers:

This is powerful stuff, it provides you with the means to do basically any thinkable modification to any system data available on the 3DS console. However, precautions are taken so you don't accidentally damage the data of your console. The write permissions system protects you by providing warnings and forces you to enter an unlock sequence for enabling write permissions. It is not possible to overwrite or modify any important stuff without such unlock sequences and it is not possible to accidentally unlock something.

As always, be smart, keep backups, just to be safe.

Installation

The recommended bootloader for use with GodMode9 is fastboot3DS. There are known issues for some users when using the standard setup based on boot9strap and Luma3DS. If you are using that setup, follow the instructions found in this guide. Here's how to set up GodMode9 (and fastboot3DS) up quickly.

• Download OpenFirmInstaller and follow the quick setup instructions found there.
• Copy the gm9 folder from the release archive to your SD card.
• Then, get good versions of seeddb.bin and encTitleKeys.bin from somewhere and put these two files into sd:/gm9/support (optional but recommended for full functionality).
  • It is also recommended you setup the RTC clock if you're running GodMode9 for the first time.
  • Find the option via HOME button > More.... Also keep in mind that you should fix your system OS clock afterwards.
  • While you're in the More... menu, you may also set screen brightness to a fixed value of your choosing and manually calibrate the touch screen (*not recommended* - try the automatic configuration first).

About support files:

For certain functionality, GodMode9 may need support files. Support files should be placed into either 0:/gm9/support or 1:/gm9/support. Support files contain additional information that is required in decryption operations. A list of support files, and what they do, is found below. Please don't ask for support files - find them yourself.

• aeskeydb.bin - Should contain 0x25keyX, 0x18keyX and 0x1BkeyX to enable decryption of 7x/Secure3/Secure4 encrypted NCCH files, 0x11key95/0x11key96 for FIRM decrypt support and 0x11keyOTP/0x11keyIVOTP for secret sector 0x96 crypto support. Entrypoints other than boot9strap or fastboot3ds may require a aeskeydb.bin file. This is now included in standard releases of GM9.
• seeddb.bin - This file is optional and required to decrypt and mount seed-encrypted NCCHs and CIAs (if the seed in question is not installed to your NAND). Note that your seeddb.bin must also contain the seed for the specific game you need to decrypt.
• encTitleKeys.bin/decTitleKeys.bin - These files are optional and provide titlekeys, which are required to decrypt and install contents downloaded from CDN (for DSi and 3DS content).

Helpful notes:

• Go here for step by steps on doing some common tasks in GodMode9. Especially users coming from Decrypt9WIP or Hourglass9 may find this to be helpful.
• Never unlock the red write permission level unless you know exactly what you're doing. You will notice that prompt when it comes up, it features a completely red screen. It is recommended you stay on the yellow permission level or below at all times to be completely safe. Also read more on the write permissions system below.

How to update GodMode9:

• Just replace GodMode9.firm on your SD card with the file found in the release ZIP.
• You may also want to update scripts, which are found in the ./gm9 folder inside the archive and go to the same folder on your SD card.

User guide

With the possibilites GodMode9 provides, not everything may be obvious at first glance. In short, GodMode9 includes improved versions of basically everything that Decrypt9 has, and more. Any kind of dumps and injections are handled via standard copy operations and more specific operations are found inside the A button menu. The A button menu also works for batch operations when multiple files are selected. A (incomplete) list of what GodMode9 can do follows below.

See also Drives in GodMode9.

Basic functionality

• Manage files on all your data storages:
  • Included are all standard file operations such as copy, delete, rename files and create folders.
  • Use the L button to mark multiple files and apply file operations to multiple files at once.
• Make screenshots:
  • Press R+L anywhere. Screenshots are stored in PNG format.
• Use multiple panes:
  • Press R+left|right. This enables you to stay in one location in the first pane and open another in the second pane.
• Search drives and folders:
  • Just press R+A on the drive/folder you want to search.
• Compare and verify files:
  • Press the A button on the first file, select Calculate SHA-256. Do the same for the second file.
  • If the two files are identical, you will get a message about them being identical.
  • On the SDCARD drive (0:) you can also write an SHA file, so you can check for any modifications at a later point.
• Hexview and hexedit any file:
  • Press the A button on a file and select Show in Hexeditor.
  • A button again enables edit mode, hold the A button and press arrow buttons to edit bytes.
  • You will get an additional confirmation prompt to take over changes. Take note that for certain files, write permissions can't be enabled.
• View text files in a text viewer:
  • Press the A button on a file and select Show in Textviewer (only shows up for actual text files).
  • You can enable wordwrapped mode via R+Y, and navigate around the file via R+X and the dpad.
• Chainload FIRM payloads:
  • Press the A button on a FIRM file, select FIRM options > Boot FIRM.
  • Keep in mind you should not run FIRMs from dubious sources and that the write permissions system is no longer in place after booting a payload.
• Chainload FIRM payloads from a neat menu:
  • The payloads menu is found inside the HOME button menu.
  • It provides any FIRM found in 0:/gm9/payloads for quick chainloading.
• Inject a file to another file:
  • Put exactly one file (the file to be injected from) into the clipboard (via the Y button).
  • Press A on the file to be injected to. There will be an option to inject the first file into it.

Scripting functionality

• Run .gm9 scripts from anywhere on your SD card:
  • You can run scripts in .gm9 format via the A button menu. .gm9 scripts use a shell-like language and can be edited in any text editor.
  • For an overview of usable commands have a look into the sample scripts included in the release archive.
  • Don't run scripts from untrusted sources.
• Run .gm9 scripts via a neat menu:
  • Press the HOME button, select More... > Scripts.... Any script you put into 0:/gm9/scripts (subdirs included) will be found here.
  • Scripts ran via this method won't have the confirmation at the beginning either.

SD card handling

• Format your SD card/setup an EmuNAND:
  • Press the HOME button, select More... > SD format menu.
  • This also allows to setup a RedNAND (single/multi) or GW type EmuNAND on your SD card.
  • You will get a warning prompt and an unlock sequence before any operation starts.
• Handle multiple EmuNANDs:
  • Press the HOME button, select More... > Switch EmuNAND to switch between EmuNANDs/RedNANDs.
  • Only available on multi EmuNAND/RedNAND systems.
• Run it without an SD card/unmount the SD card:
  • If no SD card is found, you will be offered to run without the SD card.
  • You can also unmount and remount your SD card from the file system root at any point.
• Direct access to SD installed contents:
  • Just take a look inside the A:/B: drives.
  • On-the-fly-crypto is taken care for, you can access this the same as any other content.
• Set (and use) the RTC clock:
  • For correct modification/creation dates in your file system, you need to setup the RTC clock first.
  • Press the HOME Button and select More... to find the option.
  • Keep in mind that modifying the RTC clock means you should also fix system OS time afterwards.

Game file handling

• List titles installed on your system:
  • Press HOME and select Title manager.
  • This will also work via R+A for CTRNAND and A:/B: drives.
  • This will list all titles installed in the selected location.
• Install titles to your system:
  • Just press A on any file you want installed and select Install game image from the submenu.
  • Works with NCCH/NCSD/CIA/DSiWare SRLs/ 3DS CDN TMDs/DSi CDN TMDs/NUS TMDs.
• (Batch) Uninstall titles from your system:
  • Most easily done via the HOME menu Title manager.
  • Just select one or more titles and find the option inside the Manage title... submenu.
• Build CIAs from NCCH/NCSD (.3DS)/SRL/TMD:
  • Press A on the file you want converted and the option will be shown.
  • Installed contents are found most easily via the HOME menu Title manager.
  • Where applicable, you will also be able to generate legit CIAs. Note: this works also from a file search and title listing.
• Dump CXIs/NDS from TMD (installed contents):
  • This works the same as building CIAs, but dumps decrypted CXIs or NDS rom dumps instead.
  • Note: this works also from a file search and title listing.
• Decrypt, encrypt and verify NCCH/NCSD/CIA/BOSS/FIRM images:
  • Options are found inside the A button menu.
  • You will be able to decrypt/encrypt to the standard output directory or (where applicable) in place.
• Decrypt content downloaded from CDN/NUS:
  • Press A on the file you want decrypted.
  • For this to work, you need at least a TMD file (encTitlekeys.bin/decTitlekeys.bin also required, see Support files below) or a CETK file.
  • Either keep the names provided by CDN/NUS, or rename the downloaded content to (anything).nus or (anything).cdn and the CETK to (anything).cetk.
• Batch mode for the above operations:
  • Just select multiple files of the same type via the L button, then press the A button on one of the selected files.
• Access any file inside NCCH/NCSD/CIA/FIRM/NDS images:
  • Just mount the file via the A button menu and browse to the file you want.
  • For CDN/NUS content, prior decryption is required for full access.
• Rename your NCCH/NCSD/CIA/NDS/GBA files to proper names:
  • Find this feature inside the A button menu. Proper names include title id, game name, product code and region.
• Trim NCCH/NCSD/NDS/GBA/FIRM/NAND images:
  • This feature is found inside the A button menu.
  • It allows you to trim excess data from supported file types.
  • Warning: Excess data may not be empty, bonus drives are stored there for NAND images, NCSD card2 images store savedata there, for FIRMs parts of the A9LH exploit may be stored there.
• Dump 3DS/NDS/DSi type retail game cartridges:
  • Insert the cartridge and take a look inside the C: drive.
  • You may also dump private headers from 3DS game cartridges.
  • The C: drive also gives you read/write access to the saves on the cartridges.
  • Note: For 4GiB cartridges, the last byte is not included in the .3ds file dump. This is due to restrictrions of the FAT32 file system.

NAND handling

• Directly mount and access NAND dumps or standard FAT images:
  • Press the A button on these files to get the option. You can only mount NAND dumps from the same console.
• Restore NAND dumps while keeping your A9LH/sighax installation intact:
  • Select Restore SysNAND (safe) from inside the A button menu for NAND dumps.
• Restore/dump NAND partitions or even full NANDs:
  • Just take a look into the S: (or E:/ I:) drive. This is done the same as any other file operation.
• Transfer CTRNAND images between systems:
  • Transfer the file located at S:/ctrnand_full.bin (or E:/ I:).
  • On the receiving system, press A, select CTRNAND Options..., then Transfer to NAND.
• Embed an essential backup right into a NAND dump:
  • This is available in the A button menu for NAND dumps.
  • Essential backups contain NAND header, movable.sed, LocalFriendCodeSeed_B, SecureInfo_A, NAND CID and OTP.
  • If your local SysNAND does not contain an embedded backup, you will be asked to do one at startup.
  • To update the essential SysNAND backup at a later point in time, press A on S:/nand.bin and select NAND image options... -> Update embedded backup.
• Install an AES key database to your NAND:
  • For aeskeydb.bin files the option is found in aeskeydb.bin options > Install aeskeydb.bin.
  • Only the recommended key database can be installed (see above). With an installed key database, it is possible to run the GodMode9 bootloader completely from NAND.
• Install FIRM files to your NAND:
  • Found inside the A button menu for FIRM files, select FIRM options > Install FIRM.
  • Use this with caution - installing an incompatible FIRM file will lead to a brick.
  • The FIRMs signature will automagically be replaced with a sighax signature to ensure compatibility.
• Actually use that extra NAND space:
  • You can set up a bonus drive via the HOME menu, which will be available via drive letter 8:.
  • Only available on systems that have the extra space.
• Fix certain problems on your NANDs:
  • You can fix CMACs for a whole drive (works on A:, B:, S: and E:) via an entry in the R+A button menu, or even restore borked NAND headers back to a functional state (inside the A button menu of borked NANDs and available for S:/nand_hdr.bin).
  • Recommended only for advanced users.

System file handling

• Check and fix CMACs (for any file that has them):
  • This option will appear in the A button menu if available for a given file (f.e. system savegames, ticket.db, etc...).
  • This can also be done for multiple files at once if they are marked.
• Mount ticket.db files and dump tickets:
  • Mount the file via the A button menu.
  • Tickets are sorted into eshop (stuff from eshop), system (system tickets), unknown (typically empty) and hidden (hidden tickets, found via a deeper scan) categories.
  • All tickets displayed are legit, fake tickets are ignored.
• Inject any NCCH CXI file into Health & Safety:
  • This option is found in the A button menu for any NCCH CXI file. NCCH CXIs are commonly found inside CIAs.
  • Keep in mind there is a (system internal) size restriction on H&S injectable apps.
• Inject and dump GBA VC saves:
  • Access these options in the A button menu for agbsave.bin on the S: drive.
  • Make sure you start the specific GBA game on your console before dumping or injecting the save.
  • To inject a save, it must be copied to the clipboard.
• Dump a copy of boot9, boot11 & your OTP:
  • This works on sighax, via boot9strap only. These files are found inside the M: drive and can be copied from there to any other place.

Support file handling

• Build decTitleKeys.bin/encTitleKeys.bin/seeddb.bin:
  • Press the HOME button, select More... > Build support files.
  • decTitleKeys.bin/encTitleKeys.bin can also be created/merged from tickets, ticket.db and merged from other decTitleKeys.bin/encTitleKeys.bin files via the A button menu.
• Build, mount, decrypt and encrypt aeskeydb.bin:
  • AES key databases can be merged from other aeskeydb.bin or build from legacy slot??Key?.bin files.
  • Just select one or more files, press A on one of them and then select Build aeskeydb.bin.
  • Options for mounting, decrypting and encrypting are also found in the A button menu.

Dumping games with GodMode9

Dumping games is the act of taking a game from your system or gamecart and copying it into a readable format onto your SD card. Dumping is perfectly legal if you keep the dumps to yourself, however sharing these dumps is piracy and is illegal.

This guide will tell you how to dump games from various formats and for various purposes (by PixelSergey). Dumping 3DS cartriges as .cia files is good if you want to install them to your system. Dumping them as .3ds files is good for emulators. Installed titles cannot be dumped as .3ds files. NDS cartiges can only be dumped as .nds files and cannot be installed (however, you can play them with emulators or flashcarts).

Dumping the RomFS of a game is primarily for romhacking purposess. RomFS is the place where a game stores its data. If dumped and modified, these files can be used with Luma's LayeredFS feature to patch games.

Many instructions here are adapted from Plailect's Godmode9 Usage page. This guide requires Luma3DS, b9s and Godmode9. If you do not have any of those, please follow the guide.
