[TUTO] Les meilleurs homebrews Switch en 2026 : JKSV, Tesla, sys-clk, MissionControl et overlays

A Switch running Atmosphère is much more than a console: saves, Bluetooth controllers, overclocking and overlays, here is the homebrew to have in 2026.


Before you start

You need a Switch running Atmosphère: see Hacking your Switch in 2026. Atmosphère 1.12.0 and hekate 6.5.4 support firmware 23. Applications go in sd:/switch/ and are launched from the album (homebrew menu); system modules go in sd:/atmosphere/contents/.
Careful on firmware 23: the memory available for system modules is even more limited. Install only a few at a time, and check that each one states support for 23.


Applications
  • JKSV: backs up and restores your game saves, with optional upload to Google Drive or a WebDAV server. On a game, A then A to back up; Y to restore.
  • Checkpoint (5.2.0, August 2026): the other save manager, now with automatic updates.
  • NX-Shell: a file manager. ftpd (3.2.1): an FTP server to transfer files without removing the SD card.
  • NXThemes Installer: installs themes for the menu.
  • Moonlight-Switch (1.5.0): play your PC games on the Switch, streamed from your computer.
  • RetroArch (1.22.2): retro emulators on the Switch, from the NES to the PS1.
  • Homebrew App Store: the homebrew store, convenient, but no longer updated since 2023.

System modules and overlays
  • MissionControl (0.16.0, 2 October 2026): connects over Bluetooth controllers for PS3, PS4, PS5, Xbox One and Wiimote, without an adapter. It explicitly states support for firmware 23.
  • sys-con (2.0.0): USB controllers (PS3, PS4, Xbox). Its author recommends 1.7.0 if you favor stability.
  • Tesla-Menu and nx-ovlloader: the overlay menu, opened with L + R + right stick. Get the up-to-date versions recommended by the reference guide: WerWolv's original (2023) is outdated, and error 2001-0123 indicates an overlay that is too old.
  • sys-clk (2.0.1): sets the CPU and GPU clock speeds, game by game. The reference guide advises against modified versions.
  • Status Monitor: displays clock speeds, temperature and frames per second.
  • EdiZon-SE and Breeze: cheat codes for your games.
  • ldn_mitm: local wireless play over the Internet, for games that offer it; the recommended version states compatibility with firmware 23.
  • SysDVR (6.3): streams the Switch's picture to a PC, without a capture card.

Updating the console safely

Daybreak, bundled with Atmosphère, installs a firmware update from the SD card, without going through Nintendo. Always update Atmosphère and hekate before the firmware: see our update tutorial.


Most common errors
  • Black screen or crash at boot after adding a module: remove its folder from atmosphere/contents/ using a PC, then try again one by one.
  • Error 2001-0123 when opening overlays: nx-ovlloader or an overlay that is too old.
  • A homebrew crashes when opening from the album: launch the homebrew menu by holding R while opening a game, which gives more memory.
Tgames gives no links to tools for installing downloaded games or to Switch emulators. Our other guides: RetroArch.
