3DS:Rebuild Title Database: Difference between revisions

Revision as of 21:18, 4 January 2023

This guide 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 CTR-NAND which contain the entries of all installed 3DS titles in its respective place (eg. The SD card `title.db` would contain entries of all 3DS titles installed to the SD card). For more information check out 3dbrew.

What you need

The latest release of save3ds for your operating system
The latest release of Python 3
a 3DS console with boot9strap
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 https://github.com/ihaveamac/rebuild-title-database
Click the green Code button, then click "Download ZIP" to download it
Extract the contents of the .zip into a folder
- Lets call this folder "rebuild folder"
Go to gm9 -> out on your SD card
Copy movable.sed and boot9.bin to the rebuild folder
Create a folder called 3ds in the user directory (C:/Users/[your username]/)
Copy seeddb.bin to the 3ds folder in that directory
Copy save3ds_fuse.exe from the save3ds .zip to the rebuild folder

Section II - Section II

Navigate to the rebuild folder in file explorer
Click the Address bar, then replace the address with cmd and press ENTER
- This should open a command prompt window
In the command prompt, enter the following command: py -3 -mpip install --user -r requirements.txt
Then enter the command: py -3 rebuild-title-database.py -b boot9.bin -m movable.sed -s X: -o out
- replace X: with the drive letter of your SD card, which should be inserted into your Computer
Next save3ds_fuse --db sdtitle out --import --boot9 boot9.bin --movable movable.sed --sd X:
- replace X: with the drive letter of your SD card, which should be inserted into your Computer
If you didn't get any errors, your apps should reappear, if not and they appear greyed out in System Settings -> Data Management -> Nintendo 3DS -> Software, run faketik

Troubleshooting

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
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 in it
- When you fix this, delete the out folder and try the failing command again

-* boot9.bin is missing in <code>[M:] MEMORY VIRTUAL</code>
+* Make sure you have boot9.bin and movable.sed in the rebuild folder
-** Follow the steps on [[3DS:Dump system files]] for more in-depth instructions, including other bootloaders.
+* Make sure the SD card is inserted and you can view and edit its contents
-* 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>
+* ERROR: Could not open requirements file: [Errno 2] No such file or directory: 'requirements.txt'
