• Export, import, and erase save data from DS cartridges.
• Export, import, and delete save data secure values.
• Install titles/tickets from a file system, over a local network, or over the Internet with a URL or QR code.
  • Automatically imports title seeds on installation, either from the Internet or the SD card.
• Browse and delete pending titles (downloaded updates, in-progress eShop titles, etc).
• Customize appearance by placing replacements for RomFS resources in "sdmc:/fbi/theme/".
• Only available when run from a CIA, 3DS, or a 3DSX under Luma3DS:
  • Browse and modify CTR NAND, TWL NAND, and system save data.
  • Dump the raw NAND image to the SD card.
  • Launch titles installed to the system.

Installation

Installing

Available as a CIA, 3DS, and 3DSX.

To use the 3DSX version, ensure the required services are accessible by either using Luma3DS's homebrew launcher support or running a kernel exploit beforehand, such as fasthax or waithax.

Building

Requires devkitARM, along with 3ds-curl, 3ds-zlib, and 3ds-jansson from the devkitPro pacman repository, to build.

User guide

FAQ

Q. Can I install any CIA I want?

In order to install unsigned/custom CIAs, you must be running a CFW with signature patches.

Otherwise, you can only install legitimate, signed CIAs.

Q. FBI is failing to boot or has issues as a 3DSX!

If you use Luma3DS, make sure you are running the latest version.

Otherwise, make sure to run a kernel exploit, such as fasthax or waithax, before running FBI.

Q. FBI is failing to install my CIA!

Make sure your CIA file is valid.

Also, make sure your SD card isn't a counterfeit, check for filesystem issues, and try a different SD card if possible.

How to get FBI on 3DS (Crushkai)

Changelog

2.6.1 18 May 2021

• Fix inability to cancel ext save data deletion.

2.6.0 2 Jan 2019

• Remove TitleDB support.
• Add TLSv1.2 support.
  • In testing, speeds were ~70-80kbps, which should be good enough for homebrew downloads.
    • Hope to investigate the matter further and improve speeds in the future, but wanted to finally get something out for the time being.
  • Downloads from sources that support earlier TLS versions (i.e. not GitHub) will continue to use the 3DS's built-in HTTP stack, and thus should progress at the same speeds as before.
• Revert the built-in updater back to using GitHub.

2.5.3 7 Sep 2018

• Fix lack of support for HTTP relative redirects.
• Fix multi-file actions not respecting file list filters.
• Fix title list crash related to loading the metadata of DS(i) titles.

2.5.2 21 Aug 2018

• Fix URL installation.

2.5.1 21 Aug 2018

• Add option to mark installed TitleDB entries as updated.
• Add option to sort TitleDB list by installation status.
• Display installed version and date from TitleDB cache.
• Remove CDN installer due to recent server-side changes requiring tickets.
• Titles not present in the TitleDB installation cache are no longer considered as installed by the TitleDB list.
• Fix inaccurate battery level icons.
• Fix main menu updater getting confused by another TitleDB entry named FBI.
• Fix main menu updater not updating FBI's TitleDB installation status.
• Fix potential crash from trying to display unsupported text characters.

2.5.0 23 Feb 2018

• Clean up various bits of core code.
• Fix font size on CHN/KOR/TWN devices.
• HTTP operations now support gzip/deflate compression, which should reduce bandwidth usage when supported by the server.
• Load file metadata after populating full list. Directories containing a lot of CIAs should populate faster now, although detailed information will not be immediately available for all files until loading has finished.
  • File operations for which file metadata is unnecessary should also load faster.
• Modify built-in updater to pull from TitleDB, as GitHub no longer supports TLS versions supported by the 3DS.
• Rewrite TitleDB support.
  • Titles can be installed as a 3DSX and/or a CIA, depending on availability.
    • Descriptions and categories are displayed in the main TitleDB list, and detailed information is displayed for CIA and 3DSX versions after selecting a title.
  • Entries will be blue when a newer version is available. Note that all installed titles will be marked as outdated until installed with version 2.5.0 or later through TitleDB, as the last installed version must be added to the cache.
    • All outdated titles can be updated at once by pressing Y in the TitleDB list.
  • Basic sorting and filtering options have been added.
