### Required Reading

This method of using Seedminer for further exploitation uses your `movable.sed` file to decrypt any DSiWare eShop title for the purposes of injecting an exploitable DSiWare title into the DS Internet Settings application. This requires you to already own (or download / buy) a DSiWare game from the eShop.

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

To use the [magnet](https://wikipedia.org/wiki/Magnet_URI_scheme) links on this page, you will need a torrent client like [Deluge](http://dev.deluge-torrent.org/wiki/Download).

To extract the `.7z` and `.rar` files linked on this page, you will need a file archiver like [7-Zip](http://www.7-zip.org/) or [The Unarchiver](https://theunarchiver.com/).
