<p>To dump system DSiWare, we exploit a flaw in the DSiWare Data Management window of the Settings application.</p>
<p>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.</p>
<p>For a more technical explanation, see <a href="https://github.com/zoogie/Bannerbomb3">here</a>.</p>

### 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](bannerbomb3-fredtool-(twn)) instead.

### What You Need

* Your `movable.sed` file from completing [Seedminer](seedminer)

#### Section I - Prep Work

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

1. Upload your movable.sed using the "Choose File" option
1. Click "Build and Download"

1. Insert your SD card into your computer
1. Navigate to `Nintendo 3DS` -> `<ID0>` -> `<ID1>` on your SD card

  + `<ID1>` is a 32-letter folder inside of the `<ID0>`
  ![]({{ "/images/screenshots/bb3/dsiware-location-1.png" | absolute_url }}){: .notice--info}
1. 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
1. Copy the `F00D43D5.bin` file from `BannerBomb3.zip` to the `Nintendo DSiWare` folder

1. Launch System Settings on your device
1. Navigate to `Data Management` -> `DSiWare` -> `SD Card` ([image](/images/screenshots/bb3/dsiware-management.png))

1. Power off your device
1. Insert your SD card into your computer
1. You should now have `42383841.bin` on the root of your SD card. Copy this file to somewhere on your computer, as you will use it on the next page
1. Navigate to `Nintendo 3DS` -> `<ID0>` -> `<ID1>` -> `Nintendo DSiWare` on your SD card
