Required Reading

To dump system DSiWare, 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 in order to dump the DSi Internet Settings application to the SD root.

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.

What You Need

  • Your movable.sed file from completing Seedminer

Section I - BannerBomb3

  1. Open BannerBomb3 Tool on your computer
  2. Upload your movable.sed using the “Choose File” option
  3. Click “Go”
    • This will download an exploit DSiWare called F00D43D5.bin inside of a zip file (tadmuffin_out.zip)
  4. Power off your device
  5. Insert your SD card into your computer
  6. Navigate to Nintendo 3DS -> <ID0> -> <32-character-id> -> Nintendo DSiWare on your SD card
    • This <ID0> will be the same one that you used in Seedminer
    • If Nintendo DSiWare does not exist, create it
  7. If there are any existing DSiWare backup files (<8-character-id>.bin) in this folder, move them to your PC
    • This will leave you with an empty Nintendo DSiWare folder. Moving the files to your PC ensures you dont delete any intentional backups
  8. Copy the F00D43D5.bin file from the output\Usa_Europe_Japan_Korea\ folder of the downloaded BannerBomb3 archive (tadmuffin_out.zip) to the Nintendo DSiWare folder
  9. Reinsert your SD card into your device
  10. Power on your device
  11. Launch System Settings on your device
  12. Navigate to Data Management -> DSiWare
  13. Click on the SD Card section
    • Your system should flash Magenta (pink/purple) and then crash a few seconds later. This means it worked
  14. Power off your device
  15. Insert your SD card into your computer
  16. You should now have 42383841.bin in SD root. This is the DSiWare backup you will use later in the guide
  17. Navigate to Nintendo 3DS -> <ID0> -> <32-character-id> -> Nintendo DSiWare on your SD card
    • This <ID0> will be the same one that you used in Seedminer
  18. Delete F00D43D5.bin from the Nintendo DSiWare folder and from your computer. This file will not be needed anymore
