Your own Switch games, running natively on iPhone, iPad and Mac. Game code is rewritten to native ARM64 and runs directly on the device's processor, with graphics going straight to Metal. Your whole library lives in one app, and a few clicks in the Mac or Windows launcher take a game from import to play.
Platforms: iPhone / iPad (iOS / iPadOS 18 and later) · Mac (Apple silicon, macOS 15 and later) · Build on Mac or Windows · Android / HarmonyOS coming soon · License: Apache-2.0 · Bring your own games

A native port, not an emulator
The game's own ARM64 code is rewritten at build time and then runs directly on the processor in your iPhone, iPad or Mac. There is no CPU emulator in between. Graphics calls are translated straight to Metal, and system services come from a native host. That is where the speed, the low heat and the battery life come from. Evidence
One app, your whole library
Every game you import goes into the same S2Arm app; open it and pick what to play. The whole library takes a single App slot on your developer account, so adding a game never means installing another app or spending another signing slot. Evidence
Graphical launchers, next to zero setup
There is a graphical launcher for Mac and one for Windows. On first launch the welcome page boils everything down to three steps: get this computer ready, add your keys, add your games, with a single primary button at any moment. Everything else is either bundled or fetched in one click, and you never touch a command line.
After you click Build, every stage shows its progress, elapsed and remaining time, and disk use. Several games can queue up and build one after another. Evidence
Let an AI drive
Both the Mac and Windows launchers expose a control interface, s2armctl. An AI assistant can import games, build, install, follow progress and read errors, and every step shows up in the launcher window. A companion self-check, self-fix and feedback toolkit lets the AI find a problem, apply the documented fix, and, when it cannot, package a diagnostic bundle for you to file. Watch an AI diagnose and fix a real problem end to end: Evidence
Have an AI do it for you
Send this to your AI assistant (it needs to be able to run commands on your computer):
Please read https://github.com/jhaizhou-ops/S2Arm/blob/main/launchers/macos/skill/s2arm-operator/SKILL.md and then help me install my Switch game on my iPhone.
It moves forward with a few commands, and you can watch every step in the launcher window:
/Applications/S2Arm.app/Contents/Resources/s2armctl start # open and connect to the launcher
/Applications/S2Arm.app/Contents/Resources/s2armctl next # what to do now, who does it, and why
/Applications/S2Arm.app/Contents/Resources/s2armctl diag export ~/Desktop/S2Arm-diagnostics.zip # export a diagnostic bundle if it cannot fix a problem
Anything only you can do (system permission prompts, signing in with your Apple ID, tapping Trust on your phone), the AI stops and asks you to do. On Windows, use s2armctl.cmd in the launcher folder with the same commands; exporting a diagnostic bundle is currently Mac-only.

Getting started
- Download the Mac or Windows launcher from the download page and open it. Building for iPhone on a Mac needs the free Xcode from the App Store, signed in with your Apple ID; the launcher walks you through it.
- Import your own keys and games. Put the base game, updates and DLC in one folder and import them together.
- Choose iPhone / iPad or this Mac, then click Build.
- Follow the launcher to sign and install with your own Apple ID (the Windows launcher ships with the
