Technical Details (optional)

To launch custom code, we exploit a flaw in the DSiWare Data Management window of the Settings application.

To accomplish this, we use your system’s encryption key (movable.sed) to build a DSiWare backup that exploits the system.

For a more technical explanation, see here.

Compatibility Notes

These instructions work on USA, Europe, Japan, and Korea region consoles as indicated by the letters U, E, J, or K after the system version.

If you have a Taiwanese console (indicated by a T after the system version), follow this page instead.

What You Need

  • Your movable.sed file from completing Seedminer
  • The latest release of BannerBomb3 (Release_v3.0.zip, direct download)

Section I - Prep Work

In this section, you will copy the files needed to trigger the BannerBomb3 exploit onto your console’s SD card.

  1. Power off your console
  2. Insert your SD card into your computer
  3. Open Bannerbomb3 Injector on your computer
  4. Upload your movable.sed using the “Choose File” option
  5. Click “Build and Download”
    • This will download an exploit DSiWare called F00D43D5.bin, which will be contained in a zip archive (BannerBomb3.zip)
  6. Copy bb3.bin from Release_v3.0.zip to the root of your SD card
    • The root of the SD card refers to the initial directory on your SD card where you can see the Nintendo 3DS folder, but are not inside of it
    • This file does not need to be opened or extracted
  7. Copy Launcher.dat from the folder for your model and region inside the Release .zip to the root of your SD card
  8. Navigate to Nintendo 3DS -> <ID0> -> <ID1> on your SD card
    • <ID0> is the 32-letter folder name that you copied in Seedminer
    • <ID1> is a 32-letter folder inside of the <ID0>
    • If you have multiple <ID1> folders, follow the instructions here
  9. Create a folder named Nintendo DSiWare inside of the <ID1>
    • If you already had the folder and there are any existing DSiWare backup files (<8-character-id>.bin) inside, copy them to your PC and remove them from your SD card
  10. Copy the F00D43D5.bin file from BannerBomb3.zip to the Nintendo DSiWare folder
