3DS:Alternate Exploits/Preparing menuhax67 (kartdlphax)

Required Reading

kartdlphax is an exploit for the game "Mario Kart 7", compatible with System Versions 1.0.0 through 11.16.0 for USA/EUR/JPN region consoles. It was used to launch universal-otherapp in the past, that got patched with the latest version, so this exploit can be used now to prepare unSAFE_MODE(you can find this on the main guide) or to install menuhax67 on 11.16.0-49X. If you're on an older version(<=11.15.0-47X), you can use universal-otherapp instead. This page covers installing menuhax67 to access the homebrew launcher since accessing the Homebrew Launcher from kartdlphax not possible currently.

To use this exploit, you need:

• 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)
• A physical or digital copy of Mario Kart 7 that is the same region as both consoles
• An SD card for both devices

What you need

On the source 3DS (the 3DS with custom firmware):

• The latest release of kartdlphax (plugin.3gx)
• The latest release of Luma3DS 3GX Loader Edition (boot.firm)

On the target 3DS (the 3DS that you are trying to launch the Homebrew Launcher on):

• The latest release of standard Luma3DS (the Luma3DS .zip file)
• The latest release of menuhax67 (the menuhax67 .zip file)
