This format of homebrew is also compatible with the DSi and with DS flashcarts. Alternatively, you can create a forwarder that points to the <code>.nds</code> file on your SD card, which will show up on your HOME Menu. For instructions, see [https://wiki.ds-homebrew.com/ds-index/forwarders here]. |

| == Using FBI == | | ==Installing .cia files== |
| '''FBI''' is an application that can install CIA files. To use it: | | |
| | There are 3 applications that are typically used to install 3DS software and homebrew: |
| | <tabber> |
| | |
| | |-|FBI= |
| | |
| | <span> |
| | '''FBI''' is an application that can install '''CIA''' files. To use it: |
| | |
| | <ol> |
| | <li>Place your <code>.cia</code> file anywhere on your SD card. (You may want to create a <code>cias</code> folder for organizational purposes.)</li> |
| | <li>Open the FBI application (if you followed 3ds.hacks.guide, it will be on your HOME Menu)</li> |
| | <li>Navigate to SD Card -> (wherever you put the <code>.cia</code> file)</li> |
| | <li>Navigate to <code>Install and delete CIA</code> |
| | <ul><li>The '''CIA''' file itself does not need to be kept after it is installed, hence "Install and delete"</li></ul> |
| | </li> |
| | <li>Wait for the '''CIA''' to install</li> |
| | </ol> |
| | |
| | Once the install has finished, close FBI and the application should appear as a gift box to open on your HOME Menu. If it doesn't immediately appear, you may have to power your console off and on to get it to appear. |
| | </span> |
| | |
| | |-|GodMode9= |
| | |
| | <span> |
| | <p>'''GodMode9''' is an application that can install '''CIA''' files. To use it:</p> |
| | |
| | <ol> |
| | <li>Place your <code>.cia</code> file anywhere on your SD card. (You may want to create a <code>cias</code> folder for organizational purposes.)</li> |
| | <li>Power on your 3DS while holding {{B|Start}}</li> |
| | <li>Navigate to <code>[0:] SDCARD</code> and press {{B|A}}</li> |
| | <li>Navigate to the location of the <code>.cia</code> file you want to install, then press {{B|A}}</li> |
| | <li>Navigate to <code>CIA Image Options...</code> and press {{B|A}}</li> |
| | <li>Navigate to <code>Install game image</code> and press {{B|A}}</li> |
| | <li>Unlock write permissions if prompted</li> |
| | <li>Wait for the CIA to install</li> |
| | <li>Press {{B|A}} when <code>Install success</code> appears</li> |
| | <li>Relock write permissions if prompted</li> |
| | </ol> |
| | |
| | Once the install has finished, reboot your console by pressing {{B|Start}} |
| | </span> |
| | |
| | |-|Universal Updater= |
| | |
| | <span> |
| | <p>If you followed 3ds.hacks.guide to install custom firmware on your 3DS, you probably also have '''Universal Updater''', which can be used as a homebrew app store. To use it:</p> |
| | |
| | <ol> |
| | <li>Open the Universal Updater application (the blue down arrow icon)</li> |
| | <li>Use the <code>D-Pad</code> to navigate between applications and the {{B|A}} button to select an application</li> |
| | <li>Use the <code>Search</code> or <code>Filter</code> function (the magnifying glass) to look for a specific application</li> |
| | <li>Under <code>Available Downloads</code>, select either the <code>.cia</code>, <code>.3dsx</code>, or <code>.nds</code> file, then press {{B|A}} again to install the application</li> |
| | <li>Check the queue (the button with the number in it) to see download progress |
| | <ul> |
| | <li>'''CIA''' files will appear on your HOME Menu in a gift box after you exit Universal-Updater</li> |
| | <li>'''3DSX''' files will become available in the Homebrew Launcher application</li> |
| | <li>'''NDS''' files will need to be launched from [https://wiki.ds-homebrew.com/twilightmenu/installing-3ds.html TWiLightMenu++]</li> |
| | </ol> |
| | |
| | Once the install has finished, press {{B|Start}} to exit the application, if you installed a '''CIA''' file and it doesn't immediately appear, you may have to power your console off and on to get it to appear. |

| # Place your <code>.cia</code> file anywhere on your SD card. (You may want to create a "cias" folder for organizational purposes.)
| | ==Running .3dsx files== |
| # Open the FBI application (if you followed 3ds.hacks.guide, it will be on your HOME Menu)
| | To run a piece of homebrew in <code>.3dsx</code> format: |
| # Navigate to SD Card -> (wherever you put the .cia file)
| |
| # Select "Install and delete CIA"
| |
| #* The CIA file itself does not need to be kept after it is installed, hence "install and delete"
| |
| # Wait for the CIA to install
| |
|
| |
|
| Once the install has finished, close FBI and the application should appear as a gift box to open on your HOME Menu.
| | # Place your <code>.3dsx</code> file in the <code>3ds</code> folder (NOT <code>Nintendo 3DS</code>) on your SD card |
| | #*Some pieces of homebrew may require additional support files. You may have to consult the README / documentation of that software if this is the case |
| | #The homebrew should now appear in the list of homebrew that appears when you open the Homebrew Launcher (the blue "h" icon) on your HOME Menu |
| | #*Navigate between homebrew applications / folders using the D-Pad and press the {{B|A}} button to launch it |

|
| If you followed 3ds.hacks.guide to install custom firmware on your 3DS, you probably also have Universal-Updater, which can be used as a homebrew app store. To use it:
| | ==Uninstalling software== |
|
| |
|
| # Open the Universal-Updater application (the blue down arrow icon)
| | See [[3DS:Uninstalling software]]. |
| # Use the D-Pad to navigate between applications and the (A) button to select an application
| |
| #* Use the "Search" or "Filter" function (the magnifying glass) to look for a specific application
| |
| # Under "Available Downloads", select either the CIA, 3DSX, or NDS file, then press (A) again to install the application
| |
| #* Check the queue (the button with the number in it) to see download progress
| |
| #* CIA files will appear on your HOME Menu in a gift box after you exit Universal-Updater
