3DS:Rebuild Title Database: Difference between revisions

Latest revision as of 05:45, 12 March 2024

This article will guide you in rebuilding the title.db file in your SD card.

title.db 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 title.db only has entries for titles installed to the SD card). For more information, check out 3dbrew.

What you need

The latest release of save3ds for your operating system
A version of Python 3.8 or later
A 3DS console with custom firmware
seeddb.bin

Section I - Preparing the files

Launch GodMode9 by holding START on boot
Navigate into [M:] MEMORY VIRTUAL
Press A on boot9.bin then select Copy to 0:/gm9/out
Press A to continue
Press B once to return to the main menu
Navigate into [1:] SYSNAND CTRNAND -> private
Press A on movable.sed, then select Copy to 0:/gm9/out
Turn the 3DS off
Insert the SD card into your computer
Go to the GitHub repo for Rebuild Title Database
Click the Code button, then click Download ZIP
Extract the contents of the downloaded .zip into a folder
- This folder will be referred to as the "rebuild folder" from now on
Go to gm9 -> out on your SD card
Copy movable.sed and boot9.bin into the rebuild folder
Copy seeddb.bin into the rebuild folder
Copy save3ds_fuse.exe from the save3ds .zip file into the rebuild folder

Section II - Rebuilding the Database

If you are not on Windows, replace py -3 with python3 in all commands.

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:
1. py -3 -V
  - 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.
2. py -3 -mpip install --user -r requirements.txt
3. py -3 fix-titledb.py -b boot9.bin -m movable.sed -s X:
4. py -3 rebuild-title-database.py -b boot9.bin -m movable.sed -S seeddb.bin -s X: -o out
  - replace X: with your SD card's drive letter
5. ./save3ds_fuse --db sdtitle out --import --boot9 boot9.bin --movable movable.sed --sd X:
  - replace X: 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 faketik.
- If they do not appear anywhere in the system, you should check your SD card for errors - the apps are likely gone.

Troubleshooting

boot9.bin is missing in [M:] MEMORY VIRTUAL
- Follow the steps on 3DS:Dump system files for more in-depth instructions, including other bootloaders.
The first command in Section II gave the error ERROR: Could not open requirements file: [Errno 2] No such file or directory: 'requirements.txt'
- Make sure you are in the rebuild folder and that you extracted the contents of rebuild-title-database-master.zip into it.
  - Once this is fixed, delete the out folder and try the command again.
The second or third command in Section II failed
- Make sure you have boot9.bin and movable.sed in the rebuild folder.
- Make sure the SD card is inserted and you can view and edit its contents.
