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).

### 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.
