Hello from the GenACNH Operations Team!

We hope this bulletin finds you enjoying your island getaways in Animal Crossing: New Horizons. We're here to keep you updated on the latest Nintendo Switch system update, Ver. 23.0.1, which was released on September 30, 2026.

What's Changed in Firmware Ver. 23.0.1?

In plain English, this update fixes an issue where some games or apps would take a long time to start, pause, or close. That's it - a simple but helpful tweak to keep your Switch experience smooth and enjoyable.

Important Guidance for Treasure Island Hosts & SysBot Operators

If you're running a custom firmware (CFW) on your Nintendo Switch, please be aware that Atmosphère 1.12.0 is the latest release, but it doesn't yet support firmware Ver. 23.0.1. Do NOT auto-update your custom firmware Switch consoles until Atmosphère and fusee payload files are installed on your SD card. We'll keep you posted on when it's safe to update.

Reassurance for GenACNH Users

No need to worry - all our GenACNH cloud delivery bots, item spawners, and Dodo flight lines are locked on stable firmware and are 100% operational. You can continue to enjoy our services without any interruptions.

Updating Safely for Regular Switch Players

If you're playing on a stock Switch, you can update to Ver. 23.0.1 safely by going to System Settings > System > System Update. Just follow the prompts, and you'll be all set.

Thanks for Reading, and Happy Islanding!

We hope you found this update helpful. Now, get back to your islands and enjoy the rest of your day in Animal Crossing: New Horizons. If you have any questions or concerns, don't hesitate to reach out. We're always here to help.
