<summary><em>Technikai részletek (opcionális)</em></summary>
[MSET9](https://github.com/zoogie/MSET9) is an exploit for the System Settings application developed by [zoogie](https://github.com/zoogie). 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 *any* 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.

### Kompatibilitási megjegyzések

This method requires a computer running Windows or Linux. macOS is NOT supported, nor are phones or tablets. If you do not have access to Windows or Linux, you will need to use an [alternate exploit](alternate-exploits).
{: .notice--warning}

### Amire szükséged lesz

* The latest release of [MSET9](https://github.com/zoogie/MSET9/releases/latest) (the Release `.zip` file)
* Any 3.x version of [Python](https://www.python.org/downloads/) **installed on your computer**
    + If you are on Linux, you likely already have Python 3. Ellenőrizd egy terminál megnyitásával, majd a `python3 -V` parancs megadásával. Ha ez egy verziószámot ad vissza, működni fog ezzel az útmutatóval.

    + You may see [this screen](/images/screenshots/mset9/mii-extdata.png), which indicates the necessary data has been created
    + If you just reach the normal Mii Maker screen, exit Mii Maker and continue to the next step
