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

In order to install custom firmware on our console, we need to get Homebrew Launcher access.

To accomplish this, we can use the Download Play functionality of the game Mario Kart 7, using a 3DS with custom firmware already installed along with a custom game plugin.

This custom plugin will send a hacked payload to an unhacked console, which then exploits the system in order to inject 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/PabloMK7/kartdlphax) for information about kartdlphax, [here](https://github.com/zoogie/menuhax67) for information about menuhax67, and [here](https://github.com/luigoalma/nimdsphax) for information about nimdsphax.

#### Section I - Prep Work (source 3DS)

In this section, you will set up your source 3DS (the 3DS with custom firmware) for delivery of the exploit data to the target 3DS.

1. Inserta la tarjeta SD de la **3DS de origen** en tu computadora
1. Copy `boot.firm` from the Luma3DS `.zip` to the root of the **source 3DS**'s SD card, replacing any existing file
    + La raíz de tu tarjeta SD se refiere al primer directorio de la tarjeta, donde puedes ver la carpeta Nintendo 3DS pero no estás dentro de ella
1. Copia el archivo `plugin.3gx` de kartdlphax al siguiente directorio en la tarjeta SD de la **3DS de origen**, dependiendo de la **región de tu copia de Mario Kart 7**:
    + USA: `/luma/plugins/0004000000030800`
    + EUR: `/luma/plugins/0004000000030700`
    + JPN: `/luma/plugins/0004000000030600`
    + Create the `plugins` and `00040000...` folders if they do not already exist
1. Saca la tarjeta SD de la computadora y ponla en la **3DS de origen**

#### Section II - Prep Work (target 3DS)

In this section, you will set up the files that the target 3DS will need to install custom firmware.

1. Inserta la tarjeta SD de la **3DS de destino** en tu computadora
1. Copy `boot.firm` and `boot.3dsx` from the Luma3DS `.zip` to the root of the **target 3DS's** SD card
1. Crea una carpeta llamada `boot9strap` en la raíz de tu tarjeta SD
1. Copia `boot9strap.firm` y `boot9strap.firm.sha` desde el `.zip` de `boot9strap` a la carpeta `/boot9strap/` en tu tarjeta SD
1. Copia `SafeB9SInstaller.bin` desde el `.zip` de SafeB9SInstaller a la raíz de tu tarjeta SD
1. Crea una carpeta llamada `3ds` en la raíz de tu tarjeta SD, si aún no existe
    + 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. Copy Launcher.dat from the folder for your model and region inside the menuhax `.zip` to the root of your SD card
1. Saca la tarjeta SD de la computadora y ponla en la **3DS de destino**
