3DS:Rebuild Title Database

2025-12-19T17:19:21Z

Danny8376: directly link to v1.3.0 of save3ds as latest currently have no binary release and no functional changes

This page is a guide to rebuilding the <code>title.db</code> file in your SD card.

<code>title.db</code> is the name for two files - one on the 3DS' SD card, and one on its CTRNAND - which contain a list of all installed 3DS titles for its respective part of the filesystem (e.g. your SD card's <code>title.db</code> only has entries for titles installed to your SD card). For more information, check out [[3dbrew:Title Database|3dbrew]].

===What you need===

*Release of {{GitHub|wwylele/save3ds/releases/tag/v1.3.0|save3ds}} for your operating system
*A version of [https://www.python.org/downloads/ Python 3.8 or later]
*A 3DS console with custom firmware
*{{GitHub|ihaveamac/3DS-rom-tools/raw/master/seeddb/seeddb.bin|seeddb.bin}} (direct download link)
*boot9.bin (same for all consoles) and movable.sed (specific to yours only) - dump with [[3DS:Dump system files]]

===Section I - Preparing the files===

#Turn the 3DS off
#Insert your SD card into your computer
#Go to the {{GitHub|ihaveamac/rebuild-title-database|Rebuild Title Database}} repo's page
#Click the <big>Code</big> button, then click '''Download ZIP'''
#Extract the contents of the downloaded <code>.zip</code> into a folder
#*This folder will be referred to as the "rebuild folder" from now on
#Copy <code>movable.sed</code> and <code>boot9.bin</code> to the rebuild folder
#*If you had just dumped them from your console, both are most likely in <code>sd:/gm9/out</code>
#Copy <code>seeddb.bin</code> into the rebuild folder
#Copy the <code>save3ds_fuse</code> binary from the save3ds <code>.zip</code> file into the rebuild folder

===Section II - Rebuilding the database===
{{info|If you are not on Windows, replace <code>py -3</code> with <code>python3</code> in all commands.}}

{{warning|The commands in this section are case-sensitive. Enter them exactly as written, or there may be unintended consequences.}}

#Navigate to the rebuild folder in file explorer
#Hold SHIFT and right-click anywhere in the folder's empty space, then click the option that opens a terminal, PowerShell, or Command Prompt
#In this new window, enter the following commands one at a time:
##<code>py -3 -V</code>
##*If this does not print the Python version, it is either not installed correctly, or the wrong command was used. Please read the note above.
##<code>py -3 -mpip install --user -r requirements.txt</code>
##<code>py -3 fix-titledb.py -b boot9.bin -m movable.sed -s X:</code>
##*If you are on Windows, replace <code>X:</code> with your SD card's drive letter. If you are not on Windows, replace <code>X:</code> with your SD card's mount point.
##<code>py -3 rebuild-title-database.py -b boot9.bin -m movable.sed -S seeddb.bin -s X: -o out</code>
##<code>./save3ds_fuse.exe --db sdtitle out --import --boot9 boot9.bin --movable movable.sed --sd X:</code>
##*If you are not on Windows, remove <code>.exe</code> from this command
#If you didn't get any errors, your apps should reappear on the HOME Menu immediately
#*If they only appear in '''System Settings''' -> '''Data Management''', follow '''one''' of these sets of steps based on how they appear.
#**Appear normally: Check the contents of <code>sd:/Nintendo 3DS/<id0>/<id1>/title/00040000</code>; there should only be more folders inside that folder.
#***If there is a file inside this folder, your apps are at least partially corrupted - backup your SD card to your PC, [[Formatting an SD card|reformat it]], and then try to move the backed-up files back to the SD. If this fails or the apps do not reappear afterward, [[Checking SD card integrity|check your SD card for hardware damage]].
#**Appear with a grey block count indicator and an X through their icons: Run [[3DS:Faketik|faketik]].
#**Appear with white/corrupted icons, 0 block count, and/or corrupted name: Whatever destroyed your <code>title.db</code> has also permanently corrupted your apps. Backup your SD card to your PC,[[Formatting an SD Card|reformat it]], and then [[Checking SD card integrity|check it for hardware damage]].
#*If they do not appear anywhere in the system, you may want to [[Checking SD card integrity|check your SD card for hardware damage]], as the apps are likely gone.

===Troubleshooting===

*<code>boot9.bin</code> is missing from <code>[M:] MEMORY VIRTUAL</code>
**Follow the steps to [[3DS:Dump system files|dump your system files]] for more in-depth instructions, including those for bootloaders other than [[3DS:boot9strap|boot9strap]].
*The first command in Section II gave the error <code>ERROR: Could not open requirements file: [Errno 2] No such file or directory: 'requirements.txt'</code>
**Make sure you are in the rebuild folder and that you extracted the contents of <code>rebuild-title-database-master.zip</code> into it.
***Once this is fixed, delete the <code>out</code> folder and try the command again.
*The third or fourth command in Section II failed
**Make sure you have <code>boot9.bin</code> and <code>movable.sed</code> in the rebuild folder.
**Make sure your SD card is inserted and you can view and edit its contents.
*The fifth command in Section II failed
**If you are on macOS, try installing {{GitHub|osxfuse/osxfuse/releases/latest|osxfuse}}, either via its GitHub page or via [https://brew.sh Homebrew].

====<code>Input/output error</code> on fourth command in Section II====
{{info|These instructions are for Linux users, and will not work on Windows.}}
#'''''Unmount''''' the SD card from your computer.
#Open up a terminal window, and enter the following commands one at a time:
##<code>watch lsblk</code>
##*After running this command, re-insert the SD card into your computer. The terminal window should now show a new partition of some kind. '''This is the SD card's partition'''. For example, <code>sda -> sda1</code> may have appeared after re-inserting the SD card. Keep this in mind, as you'll need it later.
##*Once you see what partition the SD card is, press <kbd><kbd>Ctrl</kbd> + <kbd>C</kbd></kbd> to stop monitoring the output of <code>lsblk</code>
##<code>fsck /dev/[partition]</code>
##*<code>[partition]</code> is the partition that showed up in the terminal, when you inserted the SD card into your computer. (e.g. <code>fsck /dev/sda1</code> if the SD card showed up under <code>sda -> sda1</code>)
##*If you see <code>fsck: command not found</code>, run the command with <code>sudo</code> (e.g. <code>sudo fsck ...</code>)

You should now be given a few prompts, containing some choices. Below are some possible prompts, and what you should answer with.
*<code>There are differences between boot sector and its backup.</code>
**Choose option 2 for "<code>copy backup to original</code>".
*<code>Orphaned long file name part "[folder name]"</code>
**Choose option 2 for "<code>leave it</code>".
*<code>Free cluster summary wrong <nowiki>(####### vs. really #######)</nowiki></code>
**Choose option 1 for "<code>correct</code>".

Eventually, you will see the following:

<nowiki>
*** Filesystem was changed ***
The changes have not yet been written, you can still choose to leave the
filesystem unmodified:
1) Write changes
2) Leave filesystem unchanged</nowiki>

If you are happy with the options you chose, and aren't scared something will break, choose option <kbd>1</kbd> to write changes. After the changes have been written, try re-running the fourth command in Section II and continuing on from there.

3DS:System Transfer/Target has CFW

2025-09-14T14:56:54Z

Danny8376:

The system transfer process is mostly the same as it would be done without CFW on either device, but you will need to use faketik at the end to restore any applications and games that did not come from the eShop.

{{Warning|text=A system transfer can only be done between two consoles that are the same region, and both must have a functional eShop! If at least one of your consoles has a nonfunctional eShop, such as after doing a region change, follow [[3DS:Movable Moveover|Movable Moveover instead]].}}

==What You Need==

*The latest release of {{GitHub|/d0k3/GodMode9/releases/latest|GodMode9}} (the GodMode9 <code>.zip</code> file)
*The latest release of {{GitHub|ihaveamac/faketik/releases/latest|faketik}} (the <code>.3dsx</code> file)

==Instructions==

===Section I - Prep Work===

*For '''both consoles''', perform the following steps:
*#Power off your device
*#Insert your SD card into your computer
*#Copy <code>GodMode9.firm</code> from the GodMode9 <code>.zip</code> to the <code>/luma/payloads/</code> folder on your SD card
*#Copy the <code>gm9</code> folder from the GodMode9 <code>.zip</code> to the root of your SD card
*For the '''source console''', perform the following steps:
*#Create a folder named <code>3ds</code> on the root of your SD card if it does not already exist
*#Copy <code>faketik.3dsx</code> to the <code>/3ds/</code> folder on your SD card
*Reinsert both SD cards into their respective consoles

===Section II - NAND Backup===

Creating a NAND backup of both consoles is a good idea in case something goes wrong. It ensures you can recover your data in the event of an error.

*For '''both consoles''', perform the following steps:
*#Press and hold {{B|START}}, and while holding {{B|START}}, power on your device. This will launch GodMode9
*#Press {{B|HOME}} to bring up the action menu
*#Select "Scripts..."
*#Select "GM9Megascript"
*#Select "Backup Options"
*#Select "SysNAND Backup"
*#Press {{B|A}} to confirm
*#*This process will take some time
*#*If you get an error, make sure that you have at least 1.3GB of free space on your SD card
*#Press {{B|A}} to continue
*#Press {{B|B}} to return to the main menu
*#Select "Exit"
*#Press {{B|A}} to relock write permissions if prompted
*#Press {{B|R|START}} to power off your console
*#Insert the console's SD card into your computer
*#Copy <code><date>_<serialnumber>_sysnand_00.bin</code> and <code><date>_<serialnumber>_sysnand_00.bin.sha</code> from <code>/gm9/out</code> to a safe place on your computer, then delete both files from the SD card
*#Reinsert the SD card into its console

===Section III - System Transfer===

#[https://en-americas-support.nintendo.com/app/answers/detail/a_id/14169 Perform the system transfer as usual]. If you are transferring from a Old 3DS to a New 3DS, choose the option '''PC-Based Transfer''' when asked, not '''Wireless Transfer''' or '''Low-Capacity microSD Card Transfer'''
#*The prompt mentioning this is not given when transferring between two Old 3DS consoles or two New 3DS consoles. These transfers are almost the same as PC-Based Transfers, but ask you to move the '''source console''''s physical SD card to the '''target console''' rather than just copy the data over. This part can be ignored without consequence, and you can copy the data between the SD cards anyway
#*If you have the option to pick a PC-Based Transfer but do not have access to a PC, be aware that during a Wireless Transfer, homebrew software, cartridge dumps, and any other data only obtainable through CFW will not be transferred over. You need to pick '''Don't Delete''' when asked about deleting Nintendo 3DS data and will need to take extra steps to reobtain the lost data.

3DS:MSET9 fresh

2024-12-12T21:35:37Z

Danny8376: fix step number

{{shortcut|3DS:M9F|3ds:MSET9F}}
==Required Reading==
If you are experiencing the "System Settings loading infinitely after reinserting the SD card" error when trying to install MSET9 using the [[3dsguide:installing-boot9strap-(mset9-play-store)#section-ii---mset9|MSET9 Play Store]] guide, this page will help you resolve that issue by swapping to a spare SD card. If you are following the [[3dsguide:installing-boot9strap-(mset9-cli)|MSET9 CLI]] guide, you should follow the normal [[3dsguide:troubleshooting#installing-boot9strap-mset9|troubleshooting]] steps instead.

All of your original games and saves will be kept intact if you follow the steps properly.

Before starting this guide, please ensure the following two things:
# You have chosen the correct model type (New vs. Old) and system version in the MSET9 setup.
#* New models have four shoulder buttons ({{B|L|ZL|ZR|R}}) and the C-Stick directly above the Y button - Old models have two shoulder buttons ({{B|L|R}}) and no C-Stick.
# You injected MSET9 in Section II Step 10, not any earlier.
#* If System Settings is stuck because you injected too early (such as in Section II Step 4), just follow the instructions for removing MSET9 and then restart from the beginning of Section II. You do not have to swap out or reformat your SD card in this case.

== Instructions ==

Follow these steps first to remove MSET9:

# Power off your console
#* If the console is infinitely loading on the extra data screen, forcibly power it off by holding down the power button for 15 seconds
# Insert your SD card into your phone/tablet/computer
# Run the '''MSET9 Installer''' application
# If <code>Remove MSET9</code> is not highlighted:
#* Tap on <code>Select "Nintendo 3DS" Folder</code>, then navigate to <code>sd:/Nintendo 3DS</code> folder on your SD card
#* Once inside the <code>Nintendo 3DS</code> folder, tap on '''Use this folder''', then '''Allow''' if asked
# Tap <code>Remove MSET9</code>
# Proceed to the next section

Danny8376: fix checkpoint link

==Required Reading==
The file <code>boot.firm</code> is what is launched by boot9strap itself after it finishes loading off of NAND. In this case, we are using Luma3DS by LumaTeam to patch the console, allowing it to run homebrew software.

This guide will have you make critical system file backups and install the following homebrew programs:

*[[3DS:FBI|FBI]] ''(installs CIA formatted applications)''
*[[3DS:Anemone3DS|Anemone3DS]] ''(installs custom themes)''
*[[Checkpoint]] ''(backs up and restores save files for 3DS and DS games)''
*[[3DS:Universal-Updater|Universal-Updater]] ''(a homebrew app store for downloading homebrew from the 3DS over Wi-Fi)''
*[[3DS:GodMode9|GodMode9]] ''(multipurpose tool which can do NAND and cartridge functions)''
*'''Homebrew Launcher Loader''' ''(launches the Homebrew Launcher)''

==What You Need==
*The latest release of [https://github.com/astronautlevel2/Anemone3DS/releases/latest Anemone3DS] (the <code>.cia</code> file)
*The v3.7.4 release of [https://github.com/BernardoGiordano/Checkpoint/releases/tag/v3.7.4 Checkpoint] (the <code>.cia</code> file)
*The latest release of [https://github.com/PabloMK7/homebrew_launcher_dummy/releases/latest Homebrew Launcher Wrapper] (the <code>.cia</code> file)
*The latest release of [https://github.com/Universal-Team/Universal-Updater/releases/latest Universal-Updater] (the <code>.cia</code> file)
*The latest release of [https://github.com/Steveice10/FBI/releases FBI] ('''both''' the <code>.cia</code> and <code>.3dsx</code> files)
*The latest release of [https://github.com/d0k3/GodMode9/releases/latest GodMode9] (the GodMode9 <code>.zip</code> file)

==Instructions==

===Section I - Prep Work===
In this section, you will copy the files necessary to follow the rest of the instructions on this page.

#Power off your console
#Insert your SD card into your computer
#Create a folder named <code>cias</code> on the root of your SD card if it does not already exist
#Copy all of the CIA files (<code>Anemone3DS.cia</code>, <code>Checkpoint.cia</code>, <code>FBI.cia</code>, <code>Homebrew_Launcher.cia</code>, and <code>Universal-Updater.cia</code>) you downloaded earlier to the <code>/cias/</code> folder on your SD card
#Create a folder named <code>3ds</code> on the root of your SD card if it does not already exist
#*This folder stores homebrew applications and data; it is different from the <code>Nintendo 3DS</code> folder that the console automatically generates
#Copy <code>FBI.3dsx</code> to the <code>/3ds/</code> folder on your SD card
#Create a folder named <code>payloads</code> in the <code>luma</code> folder on your SD card if it does not already exist
#Copy <code>GodMode9.firm</code> from the GodMode9 <code>.zip</code> to the <code>/luma/payloads/</code> folder on your SD card
#Copy the <code>gm9</code> folder from the GodMode9 <code>.zip</code> to the root of your SD card
#Reinsert your SD card into your console
#Power on your console

===Section II - Updating the System===
In this section, you will update your system to the latest version, which is safe to do with custom firmware.

#Update your console by going to System Settings, then “Other Settings”, then going all the way to the right and using “System Update”
#*Updates while using B9S + Luma (what you have) are safe
#*You may get a message saying “Your system is up to date” instead of updating. This is normal if you are already up to date; continue with the next section
#*If this gives you an error, ensure your DNS is set to "Auto-obtain", and Proxy Settings are set to “Do Not Use”
#*If this still gives you an error, [https://web.archive.org/web/20230319181423/https://3ds.hacks.guide/troubleshooting#finalizing-setup follow this troubleshooting guide]

3DS:System Transfer/Target has CFW

2023-08-29T21:39:20Z

Danny8376: Fix faketik link

The system transfer process is mostly the same as it would be done without CFW on either device, but you will need to use faketik at the end to restore any applications and games that did not come from the eShop.

If the target console does not already have CFW, follow [[../Target is stock|this guide]] instead.

== What You Need ==

* The latest release of [https://github.com/d0k3/GodMode9/releases/latest GodMode9] (the GodMode9 <code>.zip</code> file)
* The latest release of [https://github.com/ihaveamac/faketik/releases/latest faketik] (the <code>.3dsx</code> file)

== Instructions ==

=== Section I - Prep Work ===

* For '''both consoles''', perform the following steps:
*# Power off your device
*# Insert your SD card into your computer
*# Copy <code>GodMode9.firm</code> from the GodMode9 <code>.zip</code> to the <code>/luma/payloads/</code> folder on your SD card
*# Copy the <code>gm9</code> folder from the GodMode9 <code>.zip</code> to the root of your SD card
* Reinsert both SD cards into their respective consoles

=== Section II - NAND Backup ===

Creating a NAND backup of both consoles is a good idea in case something goes wrong. It ensures you can recover your data in the event of an error.

* For '''both consoles''', perform the following steps:
*# Press and hold {{B|Start}}, and while holding {{B|Start}}, power on your device. This will launch GodMode9
*# Press {{B|Home}} to bring up the action menu
*# Select "Scripts..."
*# Select "GM9Megascript"
*# Select "Backup Options"
*# Select "SysNAND Backup"
*# Press {{B|A}} to confirm
*#* This process will take some time
*#* If you get an error, make sure that you have at least 1.3GB of free space on your SD card
*# Press {{B|A}} to continue
*# Press {{B|B}} to return to the main menu
*# Select "Exit"
*# Press {{B|A}} to relock write permissions if prompted
*# Press and hold {{B|R}}, then press {{B|Start}} to power off your device
*# Insert the console's SD card into your computer
*# Copy <code><date>_<serialnumber>_sysnand_00.bin</code> and <code><date>_<serialnumber>_sysnand_00.bin.sha</code> from <code>/gm9/out</code> to a safe place on your computer, then delete both files from the SD card
*# Reinsert the SD card into its console
=== Section III - System Transfer ===

# Perform the system transfer as usual. If at all possible, choose a "PC-Based Transfer"
#* If you cannot follow a PC-Based Transfer and must instead use a Wireless Transfer, be aware that with this method, homebrew software, cartridge dumps, and any other data only obtainable with CFW will not be transferred over. If you choose a Wireless Transfer anyway, you will need to take extra steps to move over the lost data.'''Select "Do not delete" during the transfer to preserve all data on the source system, or else you will have to reobtain all lost data again by hand.'''

=== Next Steps - Branching of the Way ===
Were you able to perform a '''PC-Based Transfer''' in Section III?

# Press {{B|HOME}}, then close Download Play

{{success|text=The transfer is complete! Note that you may have to unwrap all the icons that were restored by faketik.}}

|-|No=

=== Section IV - Homebrew File Recovery ===

This section will have you manually copy all homebrew files onto the '''target console''', as wireless transfers actively refuse them.

# On the '''target console''', note all apps that should have appeared but are missing
# Insert the '''source console's''' SD card into your PC, and copy the homebrew data off of it and onto your PC
#*Everything except the <code>Nintendo 3DS</code> and <code>DCIM</code> folders is considered homebrew data
# Take out the '''source console's''' SD card but leave it out of its console, and insert the '''target console's''' SD card into your PC
# Move all of the files you copied off of the '''source console's''' SD card onto the '''target console's''' SD card
# Reinsert the '''target console's''' SD card into its console
# Redo [[3dsguide:finalizing-setup|Finalizing Setup]] on the '''target console'''. This will ensure you have backups available in case the next section goes wrong

=== Section V - Homebrew App Recovery ===
{{Section WIP|notes=Provide more detailed instructions on how to use ninfs.}}

This section will restore all games/savedata that the wireless transfer refused to copy.

# Insert the '''source console's''' SD card into your PC and mount its <code>Nintendo 3DS</code> folder using [[ninfs]]
# Copy all games/savedata that were not transferred onto the '''target console''' onto somewhere on your PC
# Unmount the '''source console's''' <code>Nintendo 3DS</code> folder and reinsert its SD card into its console, then insert the '''target console's''' SD card into your PC
# Mount the '''target console's''' <code>Nintendo 3DS</code> folder in ninfs, and add all obtained games/savedata into the existing contents
# Unmount the <code>Nintendo 3DS</code> folder, but keep the '''target console's''' SD card inserted - [[3DS:Rebuild Title Database|rebuild title.db]] to force all the new apps to appear
# Reinsert the '''target console's''' SD card into its console

{{success|text=The transfer is complete! Note that you may have to unwrap all the icons that were restored.}}

3DS:Game plugins/NTR

2023-04-26T16:51:23Z

Danny8376: /* Installing BootNTRSelector */

{{shortcut|3DS:PLG}}
NTR is a generally outdated plugin loader. However, it is still necessary to load older plugins in the <code>.plg</code> format. The only way to load NTR on modern CFW setups is using BootNTRSelector.

== Installing BootNTRSelector ==

<tabber>

|-|Universal-Updater=

=== What you need ===
* [[3DS:Universal-Updater|Universal-Updater]]

=== Installation ===
# Search for <code>BootNTRSelector</code> in Universal Updater
# Get <code>BootNTRSelector.cia</code>
#* If you are on an old 3DS and want to use plugins with extended memory mode games (such as seventh generation Pokémon games and Super Smash Bros.), also get <code>BootNTRSelector_Mode3.cia</code> as you will need to use it for such games
# Search for <code>Luma3DS (3GX)</code> in Universal Updater, and download the <code>boot.firm</code> file
# Reboot your system
# In the Luma configuration screen, select any options you need, then press START
#* Hint: If you don't know what the options are, you don't need any

|-|Manually=

=== What you need ===
* [https://github.com/Nanquitas/BootNTR/releases BootNTRSelector]
* Get <code>BootNTRSelector.cia</code>
** If you are on an old 3DS and want to use plugins with extended memory mode games (such as seventh generation Pokémon games and Super Smash Bros.), also get <code>BootNTRSelector_Mode3.cia</code> as you will need to use it for such games
* [https://github.com/Nanquitas/Luma3DS/releases The 3GX loader fork of Luma3DS]
** Even though you're running PLG format plugins, we currently require the 3GX loader version of Luma3DS for BootNTR Selector to work. You won't actually be using the 3GX loading component (unless, of course, you're using any 3GX plugins).

=== Installation ===
* Copy the BootNTRSelector .cia file(s) to your SD card
* Copy the <code>boot.firm</code> from the 3GX loader fork of Luma to the root of the SD card, replacing the <code>boot.firm</code> already there
* Insert the SD card into your system and power it on
* On the Luma Configuration screen, enable any options that you need, then press Start
** Hint: If you don't know what the options are, you don't need them
* Install the BootNTRSelector <code>.cia</code> file using FBI

</tabber>

== Using NTR plugins ==

=== Plugin location ===
If you're using the default configuration, NTR will look for plugins in the <code>plugin</code> folder on the root of your SD card. Each plugin must be inside a folder named with a game's Title ID. Inside the folder, place your .plg file.
* You can get the game's title ID from [http://3dsdb.com/ here] (cartridges), [https://hax0kartik.github.io/3dsdb/ here] (digital games), or from the <code>FBI -> Titles</code> menu. For example, Taiko no Tatsujin: Dokodon! Mystery Adventure's title ID is <code>0004000000190E00</code>, so if you wanted to use a plugin for that game, you'd create a folder named <code>0004000000190E00</code>
* The creator of the plugin may have already created a folder with the correct name for you, in which case you can just copy the title ID folder from the plugin's zip/rar/7z archive to the <code>plugin</code> folder
* If you want the plugin to run for ''all'' games (for example, for an FPS overlay), create a folder called <code>game</code> inside the <code>plugin</code> folder and place your plugin inside

An example directory for a plugin affecting one game would be <code>plugin</code> -> <code>0004000000190E00</code> -> <code>plugin.plg</code>.

An example directory for a plugin affecting all games would be <code>plugin</code> -> <code>game</code> -> <code>plugin.plg</code>.

=== Launching NTR ===
# Open the BootNTRSelector app on your home menu
# Select 3.6 on the version selection screen
#* Even if the plugin you are using says that it requires another version, try using 3.6 instead. Only use another version if 3.6 will not work
# Launch a game that you have a plugin for. You should see a green flash upon loading the game - that means that the plugin is active
# Look at the information on the plugin's webpage/README for usage instructions - usage will differ for each plugin

=== Usage notes ===
* You cannot play more than one game with NTR without rebooting the system. When you are done playing a game, power off the system
* You must launch NTR every time you wish to use a plugin
* Certain applets, such as the New 3DS's internet browser, may crash if you try to open them while NTR is active
