<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.

### Compatibility Notes

In order to follow these instructions, you will need the following:

+ A second 3DS with custom firmware (the **source 3DS**) that is the same region as the 3DS you are trying to modify (the **target 3DS**)
    + The consoles must be USA, JPN, or EUR region consoles
    + The source 3DS can be [region changed](region-changing) to match the target 3DS if necessary
+ A physical or digital copy of Mario Kart 7 that is the same region as both consoles
+ An SD card for both consoles

#### 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. Insert the SD card of your **source 3DS** in your computer
1. Copy `boot.firm` from the Luma3DS `.zip` to the root of the **source 3DS**'s SD card, replacing any existing file
    + The root of the SD card refers to the initial directory on your SD card where you can see the Nintendo 3DS folder, but are not inside of it
1. Copy kartdlphax's `plugin.3gx` to the following directory on the **source 3DS**'s SD card, depending on the **region of your copy of 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. Eject the SD card and put it in the **source 3DS**

#### 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. Insert the SD card of your **target 3DS** in your computer
1. Copy `boot.firm` and `boot.3dsx` from the Luma3DS `.zip` to the root of the **target 3DS's** SD card
1. Luo `boot9strap`-niminen kansio SD-korttisi juureen
1. Kopioi boot9strap-`.zip`-pakkauksesta `boot9strap.firm` ja `boot9strap.firm.sha` SD-korttisi `/boot9strap/`-kansioon
1. Copy `SafeB9SInstaller.bin` from the SafeB9SInstaller `.zip` to the root of your SD card
1. Luo `3ds`‑niminen kansio SD‑korttisi juureen, jos sitä ei jo ole olemassa
    + 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. Eject the SD card and put it in the **target 3DS**

#### Section III - kartdlphax

In this section, you will use Download Play to transfer the exploit data from the source 3DS to the target 3DS, which can be used to install menuhax67, a Homebrew Launcher entrypoint. Your HOME Menu settings will be temporarily inaccessible on the target 3DS while this exploit is active.

1. Power on the **source 3DS**
