<summary><em>Technical Details (optional)</em></summary>
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](https://github.com/zoogie/Bannerbomb3).

### 必要なもの
* Your `movable.sed` file from completing Seedminer or nimhax
#### セクション I - 準備
In this section, you will copy the files needed to trigger the BannerBomb3 exploit onto your device's SD card.
1. デバイスの電源を切ります
1. パソコンにSDカードを入れます
1. Open [Bannerbomb3 Injector](http://3dstools.nhnarwhal.com/#/bb3gen) on your computer
1. Upload your movable.sed using the “Choose File” option
1. Click “Build and Download”
+ This will download an exploit DSiWare called `F00D43D5.bin` and a payload called `bb3.bin` inside of a zip archive (`DSIWARE_EXPLOIT.zip`)
1. Copy `bb3.bin` from `DSIWARE_EXPLOIT.zip` to the root of your SD card
+ SDカードのルートとは、Nintendo 3DSのフォルダなどがある最初の項目のことであり、フォルダの中ではありません。
+ This file does not need to be opened or extracted
![]({{ "/images/screenshots/bb3/bb3-root-layout.png" | absolute_url }}){: .notice--info}
1. Navigate to `Nintendo 3DS` -> `<ID0>` -> `<ID1>` on your SD card
+ `<ID0>` is the 32-letter folder name that you copied in [Seedminer](seedminer)
+ `<ID1>` is a 32-letter folder inside of the `<ID0>`
+ If you have multiple `<ID1>` folders, follow the instructions [here](troubleshooting#bannerbomb3)
![]({{ "/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 `DSIWARE_EXPLOIT.zip` to the `Nintendo DSiWare` folder
