3DS:Seedminer/Mii mining

This article is not for instructions on how to use BruteforceMovable or Manual Mining.
For help with BruteforceMovable, see our custom firmware installation's page.
For help with Manual Mining, see the Manual Mining page.

Mii Mining is the name for one of two processes that allows you to find a console's movable.sed without the help of an outside resource. This method should only be used if both BFM and Manual Mining are confirmed unable to work, as it is significantly more time-consuming.

Requirements

• A computer with a dedicated GPU (graphics card) that is running Windows, macOS, or Linux.
  • Integrated graphics are too underpowered for this method, and may take upwards of a day. Both this guide and our Discord server cannot help with any issues caused by using them.

What you need

• The latest release of Seedminer (the Seedminer .zip)
• Any 3.x version of python.

Section I - Prep Work

In this section, you will obtain the console files needed to mine and set up Seedminer.

1. Extract the contents of the Seedminer .zip and move the folder inside it that matches your OS anywhere on your PC - this Seedminer folder will be where multiple other files are placed
2. While holding SHIFT, right-click anywhere in the empty space of the Seedminer folder, then click the option that opens a terminal, PowerShell, or Command Prompt
3. In the opened window, type py -3 -mpip install pycryptodomex - once it's done installing, keep the window open as you will need it later
4. Turn your device on while the SD card is inside it
5. Open the Mii Maker app
6. Tap the QR Code/Image Options button.
7. Tap Save Mii as QR Code.
8. Select any Mii Character (make a new one first if you have none), and press OK.
9. Turn the device off
10. Put the target console's SD card into your computer, navigate to the Nintendo 3DS folder on the SD, and copy the name of the 32-character-long folder directly inside
    • This folder, known as the ID0, is system-specific. Only one should be present - if you see multiple, follow these instructions.
    • Once you have the ID0, paste it into a document to reference later
11. Navigate to the DCIM folder on the SD
12. Look for the QR Code, which will be a .jpg file
    • You may have many other files in here already if you use the Nintendo 3DS Camera app
13. Copy this file to the Seedminer folder on your PC

Section II - Processing Mii QR and Mining

In this section, you will turn the Mii QR code into a usable file and mine movable.sed with it.

1. Open the editMii website on your computer
2. Click on "Import from...", then select "QR Code" and upload the Mii QR you copied to a safe place earlier
3. Click on "Export to...", then select "encrypted (.bin)", this will download a file named input.bin
4. Copy this input.bin to the Seedminer folder
5. Open the terminal/PowerShell/Command Prompt window from earlier
6. Inside this window, enter the command py -3 seedminer_launcher3.py id0 <id0>
   • Replace <id0> with the ID0 you copied into a document
7. Once it completes, enter the command py -3 seedminer_launcher3.py mii <model> <year>
   • Replace <model> with the model of your device (new or old)
   • Replace <year> with the year the 3DS was made (you often find this on the backplate) - input an estimate instead if you don't know the answer
   • If this fails with an error of input.bin is invalid size, open a Chromium browser such as Google Chrome or Edge and remake input.bin in the new browser
   • The mining process will usually take up to 90 minutes, depending on luck and your GPU's strength
8. When it finishes, a file called movable.sed will appear in the Seedminer folder - use this in place of one obtained from BruteforceMovable
