<summary><em>Technical Details (optional)</em></summary>

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 to dump the DSi Internet Settings application to the SD root.

Once we have a DSiWare backup, we can inject it into the DS Internet Settings application.

This is a currently working implementation of the "FIRM partitions known-plaintext" exploit detailed [here](https://www.3dbrew.org/wiki/3DS_System_Flaws).
