Atmosphère 1.12.2 and hekate 6.5.5: firmware 23.5.0 supported

Atmosphère 1.12.2 and hekate 6.5.5 support Switch firmware 23.5.0. Here is the order in which to update your hacked console safely.


Two updates on November 11

The Atmosphère team released on November 11, 2026 version 1.12.2 of its custom firmware, its 95th. It adds basic support for firmware 23.5.0 and stability improvements. It ships with the Homebrew Launcher (hbl 2.4.5) and hbmenu 3.6.1.
The same day, CTCaer released hekate 6.5.5 and Nyx 1.9.5. The bootloader, its interface and emuMMC also support firmware 23.5.0. The package was replaced at 20:50 UTC to fix a bug on FAT32 cards: if you downloaded it earlier, download it again.


In what order to update

• copy the contents of the Atmosphère archive and hekate's bootloader folder to the root of the SD card, replacing the files;
• also update fusee.bin if you boot with it: the old fusee-primary no longer works;
• reboot into the custom firmware, and only then update the console to 23.5.0, preferably on the emuMMC.

Caution

Atmosphère speaks of "basic" support: wait a few days for feedback if you are not in a hurry. Your system modules and overlays may also need an update: check their pages first. For the step-by-step method, see our update tutorial, and to get started, our guide to hacking your Switch. The previous version had repaired themes, DNS and modules on firmware 23.
