A full access file browser for the 3DS console

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.

Warning

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.

Quick start guide

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 insist on using that setup follow the instructions found in a certain 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 (don't ask me!) 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).
• Helpful hint #1: 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.
• Helpful hint #2: 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.

You may now run GodMode9 via holding the X Button (or any other button you chose) at startup. See below for a list of stuff you can do with it.

Buttons in GodMode9

GodMode9 is designed to be intuitive, buttons leading to the results you'd expect. However, some stuff may not be obvious at first glance. So, here's a quick, incomplete rundown of what each button / button combo does.

• <A> button: The <A> button is the 'confirm' / 'choose' button. It confirms prompts and selects entries in menus. In the main file view, it pulls up a submenu for files and opens directories (use <R+A> on directories for a submenu, also including the invaluable title search). In the hexviewer, <A> switches into edit mode.
• <B> button: The <B> button is the 'cancel' / 'return' button. Use it to leave menus without action, hold it on file operations to cancel said file operations.
• <X> button: In the main file view, the <X> button deletes (marked) files. With <R+X> files are renamed.
• <Y> button: In the main file view, the <Y> button copies and pastes files. With <R+Y> you can create folders and dummy files.
• <L> button: The <L> button is the 'mark' button. Use it with <LEFT> / <RIGHT> to mark / unmark all files in a folder, hold it and use <UP> / <DOWN> to select multiple files.
• <R> button: The <R> button is the 'switch' button. It switches buttons to their secondary function. Notable exceptions are <R+L> for a screenshot (works almost anywhere), <R+LEFT> / <R+RIGHT> to switch panes and <R+DOWN> to reload the file listing.
• <START> button: Use the <START> button to reboot from GodMode9. Use <R+START> to poweroff your 3DS.
• <SELECT> button: The <SELECT> button clears or restores the clipboard (depending on if it's empty or not).
• <HOME> button: The <HOME> button enters the HOME menu, including the scripts / payloads submenus, options for formatting the SD, setting the RTC, and more. The <POWER> button is an alternative way of entering the HOME menu.
• <R+UP> combo: This little known keycombo, when held at startup, pauses the GodMode9 boot so that you can stare at the splash screen for a little longer.
• <R+LEFT> combo: If you have installed GodMode9 as your bootloader, this keycombo enters the bootmenu. Hold on startup! If you built GodMode9 as SALTMODE and have it as a bootloader, the keycombo is simply the <START> button.

How to build this / developer info

Build GodMode9.firm via make firm. This requires firmtool, Python 3.5+ and devkitARM installed).

You may run make release to get a nice, release-ready package of all required files. To build SafeMode9 (a bricksafe variant of GodMode9, with limited write permissions) instead of GodMode9, compile with make FLAVOR=SafeMode9. To switch screens, compile with make SWITCH_SCREENS=1. For additional customization, you may choose the internal font by replacing font_default.frf inside the data directory. You may also hardcode the brightness via make FIXED_BRIGHTNESS=x, whereas x is a value between 0...15.

Further customization is possible by hardcoding aeskeydb.bin (just put the file into the data folder when compiling). All files put into the data folder will turn up in the V: drive, but keep in mind there's a hard 3MB limit for all files inside, including overhead. A standalone script runner is compiled by providing autorun.gm9 (again, in the data folder) and building with make SCRIPT_RUNNER=1. There's more possibility for customization, read the Makefiles to learn more.

To build a .firm signed with SPI boot keys (for ntrboot and the like), run make NTRBOOT=1. You may need to rename the output files if the ntrboot installer you use uses hardcoded filenames. Some features such as boot9 / boot11 access are not currently available from the ntrboot environment.

Bootloader mode

Same as boot9strap or fastboot3ds, GodMode9 can be installed to the system FIRM partition ('FIRM0'). When executed from a FIRM partition, GodMode9 will default to bootloader mode and try to boot, in order, FIRM from FCRAM (see A9NC), 0:/bootonce.firm (will be deleted on a successful boot), 0:/boot.firm, 1:/boot.firm. In bootloader mode, hold R+LEFT on boot to enter the boot menu. Installing GodMode9 to a FIRM partition is only recommended for developers and will overwrite boot9strap or any other bootloader you have installed in there.

Write permissions system

GodMode9 provides a write permissions system, which will protect you from accidentally damaging your system, losing data and/or modifying important system data. To unlock a write permission, an unlock sequence must be entered. This is not possible by accident. The write permission system is based on colors and the top bar on the top screen will change color according to the current write permission level. No permission above the yellow level can be unlocked on SafeMode9.

• Green: Modification to system files is not possible on this permission level. You can't edit or delete savegames and installed data. However, keep in mind that any non-system related or custom stuff on your SD card is not protected.
• Yellow: You can modify system files on this permission level. Data that is unique to your console and cannot be gotten from anywhere else is still not modifiable. Any damages you introduce can be fixed in software, but loss of savegames and installed data is possible if you are not careful. A NAND backup is highly recommended starting at this level.
• Orange: This is similar to the yellow permission level, but, in addition, allows edits to console unique data. Any damages you introduce are still fixable in software, but if you play around with this, having a NAND backup is an absolute requirement.
• Red: The highest regular permission level. There are no limits to system file edits, and if you are not careful enough, you can brick your console and/or remove your A9LH/B9S installation. Bricks on this level may only be fixable in hardware. If you don't have a NAND backup at this point, you seem to have a deathwish for your console.
• Blue: This permission level is reserved for edits to system memory. While, most likely, nothing bad at all will happen, consequences of edits can be unforeseen. There is even a (albeit very small) chance of bricking your console, maybe even permanently. Tread with caution on this level.

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: This 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. No need to hunt down the file!
• 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).

Fonts and translations

GodMode9 also supports custom fonts and translations as support files. These both use custom formats, fonts use FRF (Font RIFF) files which can be created using the fontriff.py Python script in the 'utils' folder. Translations use TRF (Translation RIFF) files from the transriff.py script. Examples of the inputs to these scripts can be found in the 'fonts' and 'languages' folders of the 'resources' folder respectively.

TRF files can be placed in 0:/gm9/languages to show in the language menu accessible from the HOME menu and shown on first load. Official translations are provided from the community via the GodMode9 Crowdin. Languages can use a special font by having an FRF with the same name, for example en.trf and en.frf.

Drives in GodMode9

GodMode9 provides access to system data via drives, a listing of what each drive contains and additional info follows below. Some of these drives are removable (such as drive 7:), some will only turn up if they are available (drive 8: and everything associated with EmuNAND, f.e.). Information on the 3DS console file system is also found on 3Dbrew.org.

• 0: SDCARD: The SD card currently inserted into the SD card slot. The 0:/Nintendo 3DS folder contains software installs and extdata and is specially protected via the write permission system. The SD card can be unmounted from the root directory via the R+B buttons, otherwise the SD card is always available.
• 1: SYSNAND CTRNAND: The CTRNAND partition on SysNAND. This contains your 3DS console's operating system and system software installs. Data in here is protected by the write permissions system.
• 2: SYSNAND TWLN: The TWLN partition on SysNAND. This contains your 3DS console's TWL mode operating system and system software installs. Data in here is protected by the write permissions system.
• 3: SYSNAND TWLP: The TWLP partition on SysNAND. This contains photos taken while in TWL mode.
• A: SYSNAND SD: This drive is used for special access to data on your SD card. It actually links to a subfolder inside 0:/Nintendo 3DS and contains software and extdata installed to SD from SysNAND. Crypto in this folder is handled only when accessed via the A: drive (not from 0:). This is protected by the write permissions system.
• S: SYSNAND VIRTUAL: This drive provides access to all partitions of the SysNAND, some of them critical for base system functionality. This is protected by the write permissions system, but, when unlocked, modifications can brick the system.
• 4: EMUNAND CTRNAND: Same as 1:, but handles the CTRNAND on EmuNAND. For multi EmuNAND setups, the currently active EmuNAND partition can be switched via the HOME menu.
• 5: EMUNAND TWLN: Same as 2, but handles TWLN on EmuNAND. No write protection here, cause this partition is never used on EmuNAND.
• 6: EMUNAND TWLP: Same as 3, but handles TWLP on EmuNAND.
• B: EMUNAND SD: Same as A:, but handles the 0:/Nintendo 3DS subfolder associated with EmuNAND. In case of linked NANDs, this is identical with A:. This is also protected by the write permissions system.
• E: EMUNAND VIRTUAL: Same as S:, but handles system partitions on EmuNAND. No bricking risk here as EmuNAND is never critical to system functionality.
• 7: FAT IMAGE / IMGNAND CTRNAND: This provides access to mounted FAT images. When a NAND image is mounted, it provides access to the mounted NAND image's CTRNAND.
• 8: BONUS DRIVE / IMGNAND TWLN: This provides access to the bonus drive on SysNAND. The bonus drive can be setup via the HOME menu on 3DS consoles that provide the space for it. When a NAND image is mounted, this provides access to the mounted NAND image's TWLN.
• 9: RAM DRIVE / IMGNAND TWLP: This provides access to the RAM drive. All data stored inside the RAM drive is temporary and will be wiped after a reboot. When a NAND image is mounted, this provides access to the mounted NAND image's TWLP.
• I: IMGNAND VIRTUAL: When a NAND image is mounted, this provides access to the partitions inside the NAND image.
• C: GAMECART: This is read-only and provides access to the game cartridge currently inserted into the cart slot. This can be used for dumps of CTR and TWL mode cartridges. Flash cards are supported only to a limited extent.
• G: GAME IMAGE: CIA/NCSD/NCCH/EXEFS/ROMFS/FIRM images can be accessed via this drive when mounted. This is read-only.
• K: AESKEYDB IMAGE: An aeskeydb.bin image can be mounted and accessed via this drive. The drive shows all keys inside the aeskeydb.bin. This is read-only.
• T: TICKET.DB IMAGE / BDRI IMAGE: Ticket database files can be mounted and accessed via this drive. This provides easy and quick access to all tickets inside the ticket.db. This drive also provides access to other BDRI images, such as the Title database (title.db).
• M: MEMORY VIRTUAL: This provides access to various memory regions. This is protected by a special write permission, and caution is advised when doing modifications inside this drive. This drive also gives access to boot9.bin, boot11.bin (boot9strap only) and otp.mem (sighaxed systems only).
• V: VRAM VIRTUAL: This drive resides in the first VRAM bank and contains files essential to GodMode9. The font (in FRF format), the splash logo (in PNG format) and the readme file are found there, as well as any file that is provided inside the data folder at build time. This is read-only.
• Y: TITLE MANAGER: The title manager is accessed via the HOME menu and provides easy access to all installed titles.
• Z: LAST SEARCH: After a search operation, search results are found inside this drive. The drive can be accessed at a later point to return to the former search results.

Digital preservation

GodMode9 is one of the most important tools for digital preservation of 3DS content data. Here's some stuff you should know:

• Dumping game cartridges (size < 4GiB): Game cartridges turn up inside the C: drive (see above). For most carts all you need to do is copy the .3DS game image to some place of your choice. Game images dumped by GodMode9 contain no identifying info such as private headers or savegames. Private headers can be dumped in a separate image.
• Dumping game cartridges (size = 4GiB): Everything written above applies here as well. However, the FAT32 file system (which is what the 3DS uses) is limited to 4GiB - 1byte. Take note that the .3DS game image, as provided by GodMode9 actually misses the last byte in these cases. That byte is 0xFF and unused in all known cases. It is not required for playing the image. If you need to check, we also provide split files (.000, .001), which contain all the data. If you need a valid checksum for the .3DS game image, append a 0xFF byte before checking.
• Building CIAs (all types): You may convert compatible file types (game images, installed content, CDN content) to the CIA installable format using the A button menu. To get a list of installed content, press HOME, select Title manager and choose a drive. Take note that standard built CIAs are decrypted by default (decryption allows better compression by ZIP and 7Z). If you should need an encrypted CIA for some reason, apply the encryption to the CIA afterwards.
• Building CIAs (legit type): Installed content can be built as legit or standard CIA. Legit CIAs preserve more of the original data and are thus recommended for preservation purposes. When building legit CIAs, GodMode9 keeps the original crypto and tries to find a genuine, signature-valid ticket. If it doesn't find one on your system, it will use a generic ticket instead. If it only finds a personalized one, it still offers to use a generic ticket. It is not recommended to use personalized tickets - only choose this if you know what you're doing.
• Checking CIAs: You may also check your CIA files with the builtin CIA checker tool. Legit CIAs with generic tickets are identified as Universal Pirate Legit, which is the recommended preservation format where Universal Legit is not available. Note: apart from system titles, Universal Legit is only available for a handful of preinstalled games from special edition 3DS consoles.

What you can do with GodMode9

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. For your convenience a (incomplete!) list of what GodMode9 can do follows below.

Basic functionality

• Manage files on all your data storages: You wouldn't have expected this, right? 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: Just 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): The option will turn up in the A button menu if it is 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: The option is found inside the A button menu for any NCCH CXI file. NCCH CXIs are found, f.e. inside of CIAs. Keep in mind there is a (system internal) size restriction on H&S injectable apps.
• Inject and dump GBA VC saves: Find the options to do this inside the A button menu for agbsave.bin in the S: drive. Keep in mind that you need to start the specific GBA game on your console before dumping / injecting the save. To inject a save it needs to be in 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.
