Sigpatches for Atmosphere (Hekate, fss0, fusee & package3) (2025)

CURRENT BETA SIGPATCHES UPDATED FOR FW 20.3.0 AND ATMOSPHERE v1.9.3 prerelease: Download Here

PLEASE DO NOT UPGRADE TO FW 20 UNLESS IS NEEDED NOT ALL HOMEBREW HAS BEEN UPGRADED ONE NOTORIOUS EXAMPLE IS SYS-Tweak

Given the current state of affairs, and both HarukoNX's and iTotalJustice's repositories being nuked by the almighty draconian N, I decided to open a new thread to host the up-to-date signature patches for Atmosphere through Hekate, fss0 or package3, and this pack should also handle the patches for fusee, so you can use this as an all-in-one pack (presumably).

NOTE: I (Shadow) am no longer maintaining the OP of this thread, @impeeza will now be the one in charge of updating and maintaining it.

The most recent release is attached on the post please download from there.

You can NO LONGER use OFFICIAL Atmosphere with signature patches. They're no longer supported.
You HAVE TO USE Hekate pkg3 (called FSS0 before) booting or Sys-Patch and/or use a custom build of fusee.bin with the code re-enabled, like the one made by @unicornman and Krejza9here:
https://gbatemp.net/threads/sigpatc...kate-fss0-fusee-package3.571543/post-10650031

It's highly recommended you also install Sys-Patch sysmodule to complement the sigpatches.

Troubleshooting StepsCreate IPS Patchs yourselfSYS-Patch SysmoduleHekate_ipl.ini Config


  1. Having issues running certain games after you updated the Switch's firmware, or Atmosphere's version?

    If you update to the latest CFW/sigpatches, and find yourself having issues booting some of them, be sure to check out this guide:
    https://gbatemp.net/threads/guide-how-to-fix-switch-games-not-booting-after-a-fw-cfw-update.563960/


  2. IPS Patches Creator (by MrDude):
    This program allows you to automatically create the signature patches in both IPS and Hekate's INI format for you to add to your Switch, be sure to follow the instructions and get the program from here:
    OLD REPO, NOW EXTINCT

    You can download most recent version from GBATemp Download section Also inside the program on Help Menu, Online Information item you can check for new versions

    Tutorial about use IPS Patch Creator

    This new version even allows you to create the keyset from a folder containing any Firmware version. also includes NIM patches, which are needed to connect to network on

  3. sys-patch system module (by TotalJustice):
    Thanks to @mrdude, @josete2k AND @TotalJustice There is a official new release of SYS-PATCH

    This program patches FS, ES, NIM, NFIM and Loader during the system's boot, allowing for automatic support for future versions of both firmware and Atmosphere, having a similar goal of using signature patches without actually needing IPS sigpatches files. This software would only require updating when something major breaks in firmware or Atmosphere's Loader, with the last update to the application being done since firmware version 15.0.0, and working thereafter with no needed updates to apply the patches.

    Sys-Patch Sysmodule Thread

    Latest binary including Atmosphère 1.9.1 are available on:
    https://gbatemp.net/download/sys-patch-sysmodule.39124/

    Also the source code is on:
    https://gbatemp.net/download/sys-patch-sysmodule-1-5-6-source-code.39125/

    This version have a small rewrite on the code and finally some patches where consolidated, now the names are more consistent.

    Remember the color codes of applied patches:

    Unpatched: The pattern for the code couldn't be found, so no patch applied. This may be because the patch do not apply to current version of FW or ATM, or an unsupported one.
    Patched: The pattern was found and already patched, mainly by IPS patches applied at boot by bootloader.
    Patched: The pattern was found and patched by SYS-Patch sysmodule.

    This version will run ONLY ON ATMOSPHÈRE 1.8.0 or superior. WILL NOT RUN ON ATMOSPHÈRE 1.7.1

  4. Borrowing from @impeeza hekate_ipl.ini file
    Your hekate_ipl.ini need this to launch with Patches via Hekate

    Code:

    [config]autoboot=0autoboot_list=0bootwait=0autohosoff=0autonogc=1updater2p=1backlight=100[CFW - sysMMC]pkg3=atmosphere/package3kip1patch=nosigchkemummc_force_disable=1icon=bootloader/res/icon_payload.bmp[CFW - emuMMC]pkg3=atmosphere/package3kip1patch=nosigchkemummcforce=1icon=bootloader/res/icon_payload.bmp[Stock - sysMMC]pkg3=atmosphere/package3emummc_force_disable=1stock=1icon=bootloader/res/icon_switch.bmp

Scripts to generate Signature patches automaticallySigpatches Updater by Homlet


  1. Thanks to the amazing collaborative efforts of many people in the Temp Switch threads, it is now possible to decrypt the Switch's firmware files and the Atmosphere Loader module by executing scripts for Windows/Linux/Pytho created by @mrdude with help from @crckd, @DarkMatterCore and an Anonymous user for the RE process.

    The tool to generate the sigpatches based on your firmware (FS & ES) or Atmosphere (Loader) files can be found here:
    https://gbatemp.net/threads/info-on-sha-256-hashes-on-fs-patches.581550/page-11#post-9783677

    Depending on the patches required, you can use one of 3 scripts:

    • Loader patches script. This one needs to be done for each new Atmosphere release:https://gbatemp.net/threads/autoips-sig-patcher.574126/
    • FS patches script. This one needs to be done for each new firmware release: https://gbatemp.net/threads/info-on-sha-256-hashes-on-fs-patches.581550/page-4#post-9344375
    • ES patches script. This one needs to be done for each new firmware release: https://gbatemp.net/threads/info-on-sha-256-hashes-on-fs-patches.581550/page-7#post-9354163
    Documentation related to the creation of the FS & ES patches can be found here:
    https://gbatemp.net/threads/info-on-sha-256-hashes-on-fs-patches.581550/
  2. If you want to update the sigpatches without having to deal with PC transfers, you could use the new Sigpatches Updater by @Homlet :
    https://gbatemp.net/threads/sigpatches-updater-update-your-sigpatches-from-your-switch.573546/[

Do take into consideration that I, the OP of this thread, DID NOT make these patches, and these are being uploaded as community/user submissions.
Other users make and provide these patches, and those are simply re-directed into the OP with the most up-to-date patches.
