Port your own Nintendo Switch games to Android, natively: the game's own arm64 code runs on the device, with the Switch's system services stood in for by a host and NVN graphics replayed on Vulkan. Pick the game's folder, click Port, and get an APK plus the game's data, installed on your device if you like. Bring your own game files and keys; nothing from any game is in this repository.

This is the Android port of nxnative, which does the same on iPhone and iPad. How it is put together: docs/ARCHITECTURE.md.

Each game is a profile in nxnative/dm/games/<title ID>/ with an android.tsv. Which games play, on which device, and which ones each release has been checked to port: docs/PORT_STATUS.md. The device's GPU must read BC-compressed textures (Adreno, Xclipse; not Mali or PowerVR).

1. Download nx2android-<version>-windows-x64.zip from Releases, unzip it and start nx2android.exe.
2. Setup tab: click Download missing tools (the Android NDK, the .NET SDK and platform-tools, about 1 GB, from Google and Microsoft), then set your prod.keys. Every line turns green.
3. Port tab: choose the folder with the game's NSP or XCI files (base game, update, DLC) and click Port.
4. Tick Install on the device when done with the device plugged in and USB debugging on, or copy the APK and the data folder yourself.

The step-by-step guide is packaging/INSTALL.md. You need your own game files and prod.keys, dumped from your own Switch; the tool never ships or downloads either. NSZ files must be decompressed to NSP first.

Install Python 3.11 or later and python -m pip install -r requirements.txt, then python -m porter tools --download (or install them yourself):

• Android NDK r27c (only the NDK: no Android Studio, SDK or JDK)
• .NET SDK 10
• Android platform-tools (adb), to install from the tool
• your own prod.keys, dumped from your Switch

The app:

python -m gui

Check the Setup tab, choose the game's folder (the base game NSP or XCI, its update and DLC) on the Port tab, and click Port.

Or the command line:

python -m porter doctor
python -m porter port "D:\Games\NEO" -k "D:\keys\prod.keys" --install

The APK (NeoTheWorldEndsWithYou.apk) and the data pack (NeoTheWorldEndsWithYou-data/) appear in the game folder (-o picks another). The first port takes a while (extraction, rewriting the game's code, translating its shaders); later ones reuse what has not changed. python -m porter -h lists the commands.

• porter/: the port pipeline (python -m porter).
• gui/: the desktop app (python -m gui).
• nxnative/: nxnative, kept as a git subtree of seedds/nxnative (squashed), with the Android runtime in nxnative/dm/android/ and the game profiles in nxnative/dm/games/.
• packaging/: the player's bundle (python packaging/build_bundle.py).
• devtools/: scripts for bringing up a game on a connected device (devtools/device.json names the device: {"serial": "...", "package": "..."}).
• probes/, RESEARCH.md: the feasibility study and the first on-device probes.

python -m pip install -r requirements.txt pyinstaller
python packaging/build_bundle.py

dist/nx2android/ and dist/nx2android-<version>.zip: the app, the committed nxnative/ and the install guide; no toolchains, keys or game files.
