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

[duckbill007]

@bth one more argument for your approach: if in next HOS system modules will be exec-only sys-patch won't be able to patch it.

22.1.0 works like a charm with medicine of latest sigpatches from @impeeza : https://gbatemp.net/attachments/hekate-ams-package3-sigpatches-1-10-2p-cfw-21-2-0_v0-zip.551052/

This will last at least for 2 years i think. This is the worst case but it will not happen off course. So be happy my friend.

By the way, 22.0.0 sigpatch medicine is from @Dmxjall81 :https://gbatemp.net/attachments/22-0-0-patches-zip.566245/ page 349
and 22.1.0 sigpatch medicine is from @AmeliaFox : https://gbatemp.net/attachments/patches-fw22-1-0-atmo1-11-1-zip.567005/ page 353 Thanks to them too.

that's why i have shoved it into mesosphere


i also have this funny meme (experimental) https://github.com/borntohonk/Atmosphere/releases/tag/1.11.1+Loader

Just an FYI for anyone that needs more memory for overlays or old homebrew. Kefir still comes with a 40MB fix that you can turn off and on.

I've been trying your AMS+ fork and it's pretty nice. The sigpatches being built into the CFW is great. Just works.

Is it possible to extract the fix from Kefir release and use it with vanilla Atmosphere? Or is it built into their own fork of Atmosphere?

I'm pretty sure it loads an alternate Kefirsphere that's been modified to restore the old memory map when you have it turned on.

you need to know the Atmosphère's source code changes and apply to the code, then build it from source.

Either get these and copy them over to the root of the SD card, overwriting the existing if prompted, or switch to sys-patch instead.

The thread went so off-topic I can't find it anymore. What's the reason no more sigpatches will be "officially" made?

From what I've gathered, the tool the OP used to make them with is no longer maintained and therefore they can't release them anymore. It's still possible to make them, it's just not as straightforward as it used to be. bth posted here a few scripts that can make sigpatches but I can't really help you out with how to use them, sadly.

Are Dmxjall81's patches tested?

 

[Ethelbert]

Tbh at this point Redditpatches are a meme.
Imo lock this thread, move to sys-patch...

 

[savagewarrior]

Yes both are working and looks like similar. 22.1.0 is loaded on my Version 2 switch.

And
There you download: https://github.com/Kofysh/Lockpick_RCM/releases/download/v1.9.19/Lockpick_RCM-v1.9.19.zip Unzip it to "bootloader\payloads" folder
You will need it in order to overcome 2002-1002 error in loading games and DBI prod.keys, title.keys error
Then you can update programs in switch folder such as Awoo installer 1.36

Because fusee itself no longer supports .ips patches, and if you build your own fusee to enable them, you must make your own patches, against that fusee (with the *easy* tools to do so, not being maintained). With so many people playing with these things that don't have a clue, it's not even worth the headache of trying to support it. Then there are Hekate patches, which are different... it's just easier to use sys-patch.

This new Atmosphere fork seems better still... but it remains to be seen how easy it is to keep it updated with future baseline Atmosphere when a new HOS comes out (which seems quite often since Switch2 was released).

https://github.com/borntohonk/Atmos...e/include/mesosphere/fs_patches.hpp#L196-L222
https://github.com/borntohonk/sys-patch/blob/master/sysmod/src/main.cpp#L247-L255


https://github.com/borntohonk/Atmos...ere/loader/source/exefs_patches.hpp#L201-L225
https://github.com/borntohonk/sys-patch/blob/master/sysmod/src/main.cpp#L265-L295

in terms of viability for future HOS versions, it should mostly just be refactoring ontop of upstream atmosphere, and just updating adding the same pattern-format that sys-patch currently uses.

(it also may be viable to sneak in pattern entries by text file for exefs type patches/loader patches, but since new HOS version means having to recompile one might as well hardcode it)

Hi there

My Switch had HATS-1.8.0-V1.3 with OFW 18.1.0, and I had games installed via AWOO, including sigpatches.

Now I upgraded to the latest HATS-2026-04-21-a195c24 package with Atmosphere 1.11.1 and OFW 22.0.0.

From what I understand, with this version we are suggested to use sys-patch, which seems to be included in the HATS package. However, my older games do not work. Will the sys-patch only work for the new games installed with DBI? Any way to make the previously installed games with AWOO work? Do I need to do something else to activate sys-patches?

just Run Hekate's fix archive bit on the sd card

Homebrew  Post in thread 'Atmosphere v1.11.0 released, adds support for Switch firmware 22.0.0'

Apr 22, 2026

There is some weird problem when installing with DBI now, it stops almost at the end of process and show some weird message like" Skipping file to secure partition ..."
Hope it's just DBI that need a update of some sort now...Any idea of an alternative which still work with 22.0;0?

PS: Oh wait! It seems there is one already in my package called cyberfoil....let's test and see!

PS2: It works! I managed to install Octopath Traveler 0 which was problematic with DBI...
And The Homebrew is really complete, many easy way to install things, so for people having issues with DBI now, you...

Hello guys!
I could finally start the hack system by adding the Patches-FW22.1.0-Atmo1.11.1.zip, but now I cannot run any games on the hack system, could you please help me find a solution? I'm not that smart.
