Line 1:

This ~~article will~~ guide ~~you in~~ rebuilding the <code>title.db</code> file in your SD card.

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

<code>title.db</code> is ~~a file~~ on ~~both~~ the 3DS' SD card and its CTRNAND which ~~contains~~ a list of all installed 3DS titles for its respective ~~place~~ (e.g. ~~The~~ SD card's <code>title.db</code> only has entries for titles installed to ~~the~~ SD card). For more information, check out [[3dbrew:Title Database|3dbrew]].

<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]].

{{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

Line 38:

# In this new window, enter the following commands one at a time:

## <code>py -3 -V</code>

~~##* The capital V is important. Don't use a lowercase v.~~

##* 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>

~~##* replace <code>X:</code> with your SD card's drive letter~~

## <code>./save3ds_fuse.exe --db sdtitle out --import --boot9 boot9.bin --movable movable.sed --sd X:</code>

## <code>./save3ds_fuse --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

##* ~~replace~~ <code>X:</code> ~~with your SD card's drive letter~~

# 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''' ~~and~~ they have an X through their icons ~~there, run~~ [[3DS:Faketik|faketik]].

#* If they only appear in '''System Settings''' -> '''Data Management''', follow '''one''' of these sets of steps based on how they appear.

#* If they do not appear anywhere in the system, you ~~should~~ [[Checking SD card integrity|check your SD card for ~~errors~~]] - the apps are likely gone.

#** 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, you have data corruption that this guide cannot fix - 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, [[Checking SD card integrity|check it 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.
