LemoNX
Play without JIT
JIT-less mode compiles a game's code ahead of time and signs it on your device with your own certificate. No debugger, no JIT enabler. To our knowledge, LemoNX is the first Switch emulator for iOS to do this. Set it up ↗
FOR IPHONE & IPAD
LemoNX for
iPhone and iPad.
A Nintendo Switch emulator that can run games without JIT, with a native Metal 4 renderer, on-device pairing for JIT setup, and cloud save history.
JIT or JIT-less mode · Bring your own games, keys, and firmware
No games, keys, or secrets are provided.
Native Metal 4
A renderer built directly on Metal 4, alongside the Vulkan options. Experimental: compatibility and performance vary by game and device.
Pair on your iPhone
On iOS 27, create the pairing file for JIT setup on the device itself. No computer needed. How it works ↗

RESOURCES
JIT setup Shortcut
A Shortcut for enabling LemoNX’s built-in JIT with LocalDevVPN. It downloads the developer disk image before changing connectivity, then restores the connection after the JIT attempt.
Requires LemoNX build 147 or later, LocalDevVPN, and completed pairing setup in LemoNX. Earlier builds, including the build 139 release, do not support this Shortcut.
Download Shortcut
- Open this page in Safari on your iPhone.
- Download the Shortcut, then tap the file in Files.
- Tap Add Shortcut, run it, and allow the requested permissions.
The first run needs internet access to download the developer disk image. Tested on an iPhone with build 147.
WITH THANKS

Special thanks to Stossy (Stossy11) for creating MeloNX. Without his work, none of this would be possible.
Thank you to the Nextendo team for the online service, and to the Ryujinx, Ryubing, and MeloNX contributors, the developers whose work we build on, and everyone helping with testing and artwork.
