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

To install boot9strap on your console, we derive your console's unique encryption key. To accomplish this, we use a tool called Seedminer to calculate the data encryption key (movable.sed) for your console.

Once we have `movable.sed`, we can edit the SD card data of the game Mario Kart 7 to install menuhax67, which will allow us to get Homebrew Launcher access.

Once we have Homebrew Launcher access, we can run nimdsphax to install boot9strap.

See [here](https://github.com/zoogie/kartminer7) for information about Kartminer7, [here](https://github.com/zoogie/menuhax67) for information about menuhax67, and [here](https://github.com/luigoalma/nimdsphax) for information about nimdsphax.

#### Section I - Preparing Mario Kart 7 data

In this section, you will have the 3DS generate some data in Mario Kart 7 that will be used to install the exploit in a later section.

1. Reinsert your SD card into your console
1. Open Mario Kart 7
1. Tap the "Mario Kart Channel" button on the bottom

#### Section II - SD Card Prep Work

1. Pasang kad SD anda ke dalam komputer
1. Copy `boot.firm` and `boot.3dsx` from the Luma3DS `.zip` to the root of your SD card

1. Create a folder named `boot9strap` on the root of your SD card
1. Copy `boot9strap.firm` and `boot9strap.firm.sha` from the boot9strap `.zip` to the `/boot9strap/` folder on your SD card
1. Copy `SafeB9SInstaller.bin` from the SafeB9SInstaller `.zip` to the root of your SD card
1. Create a folder named `3ds` on the root of your SD card if it does not already exist
    + This folder stores homebrew applications and data; it is different from the `Nintendo 3DS` folder that the console automatically generates
1. Copy the `nimdsphax` folder from the nimdsphax `.zip` to the `/3ds/` folder on your SD card
1. Copy `menuhax67_installer.3dsx` from the menuhax `.zip` to the `/3ds/` folder on your SD card

1. Double-click on the BACKUP `.bat` file corresponding to your console's region (e.g. backup_USA.bat if you have a USA copy of Mario Kart 7)

    + If you get a message from Windows Defender, click "More info", "Run anyway", then press any key to continue
    + If the backup was successful, you should see a new folder appear
    + If you wish to restore this data at a later date (after finishing this guide), insert your SD card and double-click on the RESTORE `.bat` file corresponding to your console's region
1. Go back to the Release_BETA_mk7 folder, then double-click on the `.bat` file corresponding to your console's region (e.g. USA.bat if you have a USA copy of Mario Kart 7)
