This page is a guide to transferring data between systems without doing a System Transfer, and usually should only be done if the source console you are transferring from is nonfunctional or you only have its SD.
If you do not have a specific reason to follow this guide (i.e. both consoles are usable), do a System Transfer instead.

Required Reading (Do NOT ignore)

This guide can potentially cause unexpected results if done wrong. Please ensure you read the steps carefully to prevent these unexpected results from happening.
Additionally, ensure you have read the following three warnings to have a full understanding of the potential risks of this guide.

Do NOT use a movable.sed from Bruteforce Movable as your system movable (in general, but especially not for this guide). Doing so may cause other issues with the system, and WILL result in a guaranteed brick if you uninstall CFW while using that movable. Always keep a backup of your original movable.sed if you do so.

If you have already done this guide at any time before the date 2024-08-11, then uninstalling CFW will brick your console, as FixupMovable (which is done by the script) is required to avoid crashing on stock firmware. If this applies to you, you can fix stock firmware by booting into GodMode9, copying your movable.sed from 1:/private to the destination console's SD root, copying MMM.gm9 to the /gm9/scripts/ folder on the SD card, and then doing the instructions from Section II onward on the destination console only.

Any games/savedata/themes/DSiWare that was already on the destination console's SD card will become inaccessible once the guide is completed - you will only be able to use the data transferred over from the source console. To access the destination console's data again, you must undo the moveover. The script extracts the original versions of those files so you are able to undo it if you need to - do not lose those files.

If the above warning will cause issues for you and you are willing to take extra steps to avoid it, you can instead use ninfs to merge the source console's encrypted files onto the destination console, then rebuild title.db to make any merged games/apps appear. However, note that even this method will not bypass the issues of using a Bruteforce Movable movable.sed.

If you are confused in any way, join the Nintendo Homebrew Discord and ask for help in the 3ds-assistance channels.

What You Need

• Two 3DS consoles, both modded with Luma3DS
  • These will be referred to as the source console and destination console for this guide's purposes
  • If either console is not currently modded, stop and mod it with our custom firmware installation guide first
• The source console's essential.exefs, such as the one created in our guide's Finalizing Setup
  • If you already have the source console's movable.sed outside of a .exefs file, you can use that directly
• The latest version of faketik (the .3dsx file)
• The latest version of GodMode9 (the GodMode9 .zip file)
• The latest version of MMM.gm9
• To download, right-click/long-press the page and select Save page as... or similar, then rename the downloaded file to MMM.gm9 if it is not already named that

Instructions

Section I - Prep Work

Follow these instructions on the destination console only.

1. Power off your console and insert your SD card into your computer
2. Copy GodMode9.firm from the GodMode9 .zip to the /luma/payloads/ folder on your SD card
3. Copy the gm9 folder from the GodMode9 .zip to the root of your SD card
4. Copy MMM.gm9 to the /gm9/scripts/ folder on your SD card
5. Create a folder named 3ds 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 Nintendo 3DS folder that the console automatically generates
6. Copy faketik.3dsx to the 3ds folder on the root of your SD card
7. Copy the source console's essential.exefs to the root of your SD card and rename it to old-essential.exefs
   • If you have the source console's movable.sed already in raw form, you can copy that file to the root of the SD card instead
8. Reinsert your SD card into your console

Section II - Setup Script

1. Hold Start, and while holding Start, power on your console
2. Your console will have booted into GodMode9
3. If you are prompted to create an essential files backup, press A to do so, then press A to continue once it has completed
4. If you are prompted to fix the RTC date&time, press A to do so, then set the date and time, then press A to continue
5. Press Home to bring up the action menu
6. Select “Scripts…”
7. Select “MMM”
8. Follow the prompts in the script, answering any questions that you are asked
9. Once the script completes your console will have rebooted
10. Your console may act like it has just been formatted - this does not mean your data has been lost. If it does this, proceed normally through initial setup and get to the HOME Menu

The destination console's original essential.exefs and movable.sed files will be in sd:/gm9/out/MMM_Backup on its SD card. It is highly recommended to back up these files to a safe location.

Section III - Reinstating Apps

1. Launch the Download Play application
2. Wait until you see the two buttons
   • Do not press either of the buttons
3. Press L+↓+SELECT at the same time to open the Rosalina menu
4. Select Miscellaneous options
5. Select Switch the hb. title to the current app.
6. Press B to continue
7. Press B to return to the Rosalina main menu
8. Press B to exit the Rosalina menu
9. Press HOME, then close Download Play
10. Relaunch the Download Play application
11. Your console should load the Homebrew Launcher
12. Launch faketik from the list of homebrew
13. Wait until the process is completed
14. Press START to exit
15. Reboot your console

The moveover is complete. Congratulations for performing a complex procedure.
