It's the first Nintendo Switch firmware update of 2024. Made available as of today is system software version 18.0.0, marking a new milestone. According to the patch notes, not much is brought to the table in this update, which features a new timer option for auto-sleep, and Korean as a supported language for the Nintendo Switch Parental Controls video. Under the hood, however, it looks there there's some substance, as it has broken support for Atmosphere. SciresM says that it'll take a few days to get around to, but expect to see a new Atmosphere update that supports version 18.0.0 in the near future.

Ver. 18.0.0 (Released March 25, 2024)​

• Added “15 Minutes” as an option for “Auto-sleep when playing on TV” in Sleep Mode Settings.
• Added Korean as a supported language for “Nintendo Switch Parental Controls” introductory video.
  • When the console language is set to Korean, the video can be accessed from Settings > Parental Controls.
• General system stability improvements to enhance the user's experience.

This is a major update, so Atmosphere will be broken until updated.

I've been traveling in Japan since earlier in the month, but I get back this week -- I'll start sorting out getting Atmosphere updated as soon as I can, but it might be a couple days before I can get started. https://t.co/ELLRWrz7Xg

I got a question, How can you downgrade a EmuNAND or even a SysNAND from firmware 18.0.0 to 17.0.1 if nobody have the new set of keys? you need the keys to read the new (Emu)NAND.

Or Am I mixing two different concepts?

Just tried emummchacgen and it can't read the NCA, are you thinking they changed the key dumping to make it harder to get em for Yuzu?

Wait, I tried with a new firmware download, and that worked.

The better answer is to restore a NAND backup actually.

You were able to downgrade FW back to 17 with emmchaccgen? Please explain what you did exactly.
edit- Guess they didn't want to explain, or just full of it!

 

[TomSwitch]

If this is true then it's safe to downgrade? I won't get banned if I do so?

off course you will be if Nintendo caught you

Your emotional support animal updated your Switch, so typical.

Atleast you didn't said your cat updated your switch lol.

 

[TomSwitch]

Korean language added for the Nintendo Switch parental controls, huh? Now Koreans are happy.

It's actually to try out new keys. Nintendo loves new keys and they can't help themself from adding more.

If you're already trying to update to 18.0, you might have brain damage.

Is this even possible anymore? Hasn't Nintendo DMCA'd all the relevant projects for hacking Switch?

We hope they can not DMCA Atmosphère because Atmosphère do not break any of the rules.

Yeah, neither did suyu, but... look what happened.

That isn't what he meant, he meant what SciresM provide doesn't enable piracy since he never included the signature patches.

As for Suyu of course they will go after emulator to stop people from running switch games on emulator. Same reason for Nintendo going after lockpick and sig patches.

 

[impeeza]

Suyu does break the invented rules of Ninti because "it can be used to overpass the protection measures." Plain Atmosphère can not be used to bypass protections.

 

[linuxares]

Couldn't you just run Lockpick/Picklock and get your new keys? (If it still works on 18.)

Not the new key sadly

Sorry, I already updated to 18.0.0. And my console is not modded.

I just downgraded my swith lite from v18 to 17 via this guide

suyu is using Nintendo's yuzu code
