Atmosphere 签名补丁（Hekate、fss0、fusee 与 package3）更新支持 FW 21.2.0 与 Atmosphere v1.10.2 prerelease

CURRENT BETA SIGPATCHES UPDATED FOR FW 21.2.0 AND ATMOSPHERE v1.10.2 prerelease: Download Here

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.

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:

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
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

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

Code:

[config]
autoboot=0
autoboot_list=0
bootwait=0
autohosoff=0
autonogc=1
updater2p=1
backlight=100

[CFW - sysMMC]
pkg3=atmosphere/package3
kip1patch=nosigchk
emummc_force_disable=1
icon=bootloader/res/icon_payload.bmp

[CFW - emuMMC]
pkg3=atmosphere/package3
kip1patch=nosigchk
emummcforce=1
icon=bootloader/res/icon_payload.bmp

[Stock - sysMMC]
pkg3=atmosphere/package3
emummc_force_disable=1
stock=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
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/
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.

Linked old thread to this one. Thanks for making a dedicated thread. If you ever feel like passing it on to someone else, let me know and I'll link to that instead.

Thank you
Much appreciated

After a whole day spent fighting this problem of sigpatches (nobody had them complete) I managed to solve it with this thread.

Thank you all very much, I am new to this community and I really appreciate your work.

I managed to reinstall and fix many corrupted games with no problem.

Tested on CFW 10.1.0 AMS 0.14.1 emuMMC fusse-secundary

Shadow are you going to be the 1 updating the sigpatches? Or just re-posting them?

Reposting them.
I don't have the knowledge required to update them myself, so I will still rely on people making them.
I will maintain the OP updated tho as soon as new patches are done.

@ShadowOne333 Thank you very much^^
Just updated one of my switches emuNand from FW 9 with Kosmos to 10.1.0 and Atmosphere v0.14.1.
All went fine, the patches working well, thanks

Same here, I updated my switch from an old SXOS 9.1 by a complete wipe and moving to EmuMMC with DeepSea 1.5.1 and these patches and it works nicely.

I am so confused. I use Hekate to boot info fss0/emmuc, but these patches don't work for me. I installed the fusee-primary patches and those *do* work. How can that be?

I used the "NH Switch Guide" to get set up, if that helps.
