<p><ahref="https://github.com/zoogie/MSET9">MSET9</a> is an exploit for the System Settings application developed by <ahref="https://github.com/zoogie">zoogie</a>. It exploits a flaw where the ID1 (the second 32-character folder name inside of the Nintendo 3DS folder, inside of the ID0) can be <em>any</em> name as long as it is 32 characters. Performing a specific sequence of actions results in the console executing the instructions that are encoded into the ID1 folder name, which can be used to grant full control over the 3DS.</p>
