<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.

  + ![]({{ "/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
