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

This method of using Seedminer for further exploitation uses your `movable.sed` file to decrypt any DSiWare title for the purposes of injecting an exploitable DSiWare title 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).
