|
[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.

### Compatibility Notes
|
||
|
|
|
||
|
|
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}
|
||
|
|
|
||
|
|
### What You Need
|
||
|
|
|
||
|
|
* The latest prerelease of [MSET9](https://github.com/zoogie/MSET9/releases) (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. Check by opening a terminal and entering `python3 -V`. If this returns a version number, it will work for this guide.

||
|
|
1. Power on your console **with your SD card inserted**
|
||
|
|
1. Open Mii Maker
|
||
|
|
1. Wait for your console to reach the "Welcome to Mii Maker" screen, then exit Mii Maker
|
||
|
|
+ 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
