Tutorial How to build Overlays from Code

When new version of Atmosphere is deployed, sometimes new LibNX is used and in some cases make overlays do not load or crash Tesla loading. so you need to compile the source code using the latest LibNX

For that you need a DevKitPro environment, under Linux is very easy to setup one, for Windows I do prefer to use MSYS, because is a closed setup do not affected by any software you have on your PC and can be recreated very easy.

I have a tutorial about to setup a DevKitPro environment using MSYS https://gameparadise.org/tutorials/setup-a-devkitpro-environment-on-windows.172/ is easy and quick.

Once you have a working DevKitPro you neeed to install the packages required, for most to the current OVLs you need:

Open MinGW64



And run the next command:

pacman -Syuu --needed --noconfirm git make libnx devkitA64 switch-tools devkita64-rules


And here is where the plot twist, Also sometimes the official LibNX package is not updated yet to latest one on Atmosphere, so you need to build and install the most recent version of LibNX for that you can run the next commands:


After some minutes you will have the most recent version of LibNX installed.


This step is not always needed you can check on the repository if there is new commits after the most recent release or a PR from Atmosphère developers





Once you have all requisites in place you can clone the repository and execute the command make

Each overlay have his own repository, the most used Overlays are:


InfoNX - Shows current information and stats, also can enable «Reduced battery wearing» when docked
Repo: https://github.com/renA21/InfoNX/

DNS-MITM_Manager - Allows you edit DNS-MiTM files
Repo: https://github.com/znxDomain/DNS-MITM_Manager

EdizonOverlay - Manage cheats for the current title and also can show some System Information
Repo: https://github.com/proferabg/EdiZon-Overlay

Emuiibo - Allow you to manage the status of emulated amiibo

ldn_mitm - Allows you to enable disable and setup LDN MiTM service to use LAN-Party over the internet
Repo: https://github.com/DefenderOfHyrule/ldn_mitm/

OvlSysmodules - Enable/Disable, Start/Stop Sysmodules on your console
Repo: https://github.com/WerWolv/ovl-sysmodules

QuickNTP - Allow to sync your clock with NTP server over the network
Repo: https://github.com/nedex/QuickNTP

Repo: https://github.com/HookedBehemoth/ShareNX-Overlay

Status-Monitor-Overlay - Enable a floating overlay showing statistics about the console.
Repo: https://github.com/masagrator/Status-Monitor-Overlay/releases (Also you can use the latest release on repo)

Studious-Pancake (full) With Mariko support - Shows a menu of possible payloads and settings for reboot to.

All the overlays can be build using this commands:


By example to build InfoNX you execute:




Now you can copy the built OVL file to your console.


Also there is a set of software needed to run the overlays:
First and most important is the Tesla Sysmodule, this Atmosphère's sysmodule enable the use of overlays
Originally developed by @WerWolv then the torch was taken by @zdm who tweak the code.
More information: https://gbatemp.net/threads/tesla-the-nintendo-switch-overlay-menu.557362/ and https://tesla.werwolv.net/, https://github.com/WerWolv/nx-ovlloader/releases

In order to build the sysmodule you need to execute the commands:


The NX-Overlay Sysmodule, loads the main menu of overlays, called Tesla Menu, that menu should exist on the path SDMC:/switch/.overlays/ovlmenu.ovl (WITH THAT EXACT NAME)
This Overlay Menu (TESLA - Menu) is developed by @WerWolv the original repository is: https://github.com/WerWolv/Tesla-Menu and can be build with the commands:
