Last week, NIntendo released a major update to their Switch firmware, with the latest now being version 19.0.0. This update brought a significant amount of changes under the hood, breaking compatibility with the Atmosphere NX custom firmware.

Today, the Atmosphere NX developer @SciresM has updated the custom firmware to support this latest v19.0.0 official firmware, with the CFW's pre-release version now being pre-1.8.0 for Atmosphere. This new pre-release adds basic support for firmware 19.0.0, but not all modules have been fully updated to the latest changes, as these will come with the proper 1.8.0 release.

The changelog for version pre-1.8.0 is the following:

1.8.0 is Atmosphère's eightieth official release.
Please be sure to update fusee when upgrading to 1.8.0. fusee-primary no longer exists, and will not work any more.
Please note: Atmosphère 1.8.0 is currently in pre-release, and issues may be found that need to be fixed before full release.

• If any bugs are reported while Atmosphère is in pre-release, they will be fixed and the build will be updated.
• 1.8.0 will transition to release after a short amount of time has passed without pressing bug reports.

With thanks to the @switchbrew team, Atmosphère 1.8.0 is bundled with hbl 2.4.4, and hbmenu 3.6.0.
The following was changed since the last release:

• Basic support was added for 19.0.0.
  • The console should boot and atmosphère should be fully functional. However, not all modules have been fully updated to reflect the latest changes.
    • There shouldn't be anything user visible resulting from this, but it will be addressed in a future atmosphère update. There is still one action item from 18.0.0 to be addressed, as well.
  • exosphère was updated to reflect the latest official secure monitor behavior.
  • mesosphère was updated to reflect the latest official kernel behavior.
  • loader was updated to reflect the latest official behavior.
  • pm was updated to reflect the latest official behavior.
  • ro was updated to reflect the latest official behavior.
• creport's file acces patterns were optimized, greatly improving performance when generating a crash report.
• Atmosphère now uses relr relocations where possible.
  • This reduces the filesize of a number of atmosphère's modules.
• A number of minor issues were fixed and improvements were made, including:
  • Support was fixed for running Atmosphère on newer units with specific Hynix/Micron DRAM chips.
• General system stability improvements to enhance the user's experience.

For information on the featureset supported by 1.8, please see the official release notes.

Any issues or bugs related to this new version of Atmosphere should be properly addressed in Atmosphere NX's GitHub repository for proper debugging.

Somebody have to ask this... do you think down the line Nintendo is going to do a cease and desist to Atmosphere ?

We all thought Ryujinx wouldn't be touched but they were.

Now you jinxed it. So yeah. It'll be on you!

Please look forward to it.

I'm just being honest because the CFW userbase is very little compared to the Steam Deck / ROG Ally / Handheld PC markets...

Time to update my switch before my dog does.

See, folks? I told you Atmosphere was going to be updated to work with the latest firmware. To think last time you were all whining about your precious homebrew stuff on your Switches...

 

[FFTW]

Good to know. How long does it normally take between a pre-release and a full release btw?

Depends on how much stuff was added in.
Nintendo has a tendency to do major updates to a lot of the Switch's modules when they update their SDK, so it depends on how many of these modules where touched by the update. It should be longer than a few days or a week or so maybe.

Keep on yapping kiddo
Literally nobody doubted SciresM will come forward with an update.

 

[chocoboss]

Updated from 16.0 to 18.1.0 Yesterday

 

[shanefromoz]

It was available a week ago, I’ve been using this for a week

Thats great. Does it work with the normal sigpatches or do we need to do something else also?

 

[Blythe93]

Not sure about Ryujinx, but I'm sure that SciresM is doing his best not to provoke big N in order for Atmosphere to remain up and in active development.

CFW isn't illegal, and Ryujinx didn't get C&D, they sold out.

Why wouldn't it?

 

[SDA]

Why wouldn't it?

Because someone quoted me that time saying this:

What would happen if Michael decided to spend time with a beautiful girlfriend in a cabin away from society for a few months without connecting to the internet and without knowing that updates existed, how long would people hold their breath without its atmosphere?

I believe Ryujinx got on Nintendo's radar when people were uploading images/videos of it running Echoes of Wisdom weeks before its official release.

 

[Memfis]

Five words:
Great work. Thank You SciresM

 

[BlusterBong]

Meanwhile the Sudachi dev quitting by choice isn't news, wonder why?

 

[LokeYourLord]

Meanwhile the Sudachi dev quitting by choice isn't news, wonder why?

The guy and his Yuzu fork has been around about as long as a wet fart stays in the air. He's worked on it for such a short amount of time, that it may as well count as a ripoff + rebrand in terms of what he did. He hasn't really "earned" being newsworthy in any significant way yet because he quit after an amount of time that is shorter than your average TikTok'ers attention span.

So yeah, it's simply not worth any news because barely anyone paid attention to the emulator or its developer since it wasn't even around long enough for a goldfish to remember and forget about it again, and thus it never picked up any traction. Now, if he would've worked on this for a year at this point already, then it might be a different story, but I know people that have had a cold for longer than this emulator was being worked on...

SciresM is such a legend for making this available for all of us.
