A static recompilation of The Legend of Zelda: Breath of the Wild (Nintendo Switch, versions 1.0.0, 1.6.0 and 1.8.2) for Android. This is not emulation: the game's ARM64 code becomes C compiled for your phone, and its graphics (NVN) are translated to Vulkan.

It is built on the engine of LAS Recomp by peiikai (a recompilation of Link's Awakening) and its Android port, LASRecompAndroid.

Android is the only application target. Desktop ports and packaging were discontinued on 2026-10-22. Windows, Linux or macOS may still be used as development hosts with the Android SDK/NDK.

• Playable from the title screen into the world, with saves, on the POCO F7 Ultra: 1.0.0 and 1.6.0 at 30 fps, 1.8.2 at 30 or up to 60 (about 40-47 fps in the open world with a Turnip driver).
• 1.8.2 has Brazilian Portuguese, widescreen (Video > Aspect ratio "Unlocked": the view widens, the HUD goes to the screen's edges) and SavageWindRecomp's frame pacing.
• Video: internal resolution, AMD FSR 1 / Snapdragon GSR 1 upscaling, output resolution, SMAA.
• App: game files set up from the phone (each version in its own folder, switched on the Game Files page), touch controls, controllers, mods, menus in English and Portuguese, Vulkan driver choice (Turnip via adrenotools) and driver compatibility options.
• Known gaps: setting the game up on the phone compiles the game code there, and that has not been timed or tested with BOTW yet (expect a long wait and a hot phone); GPUs other than Adreno 8xx take slower, safer paths; thumbnails of saves made in the app are black; the audio still uses a simplified mixer.

1. Download the APK from Releases and install it (Android 11+, arm64, Vulkan; about 30 GB free per game version).
2. Open it, go to Set up game files and choose the folder with your exefs and romfs. The version is told from the files. The app copies what it needs and builds the game code on the phone.
3. On Adreno phones, a Mesa Turnip driver (Settings > Files > Vulkan driver) runs the game much faster than the system driver. If the app stops at start with "Vulkan driver is too old", long-press the app icon and choose Choose driver to pick one before the game starts.

With the Android SDK / NDK, a phone on adb and your dump in Dump/:

cd android/botwrecompandroid && ./gradlew assembleDebug    # the app
android/build_gamelib.sh Dump/01007EF00011E000/exefs  # the game code (about an hour)
android/push_game.sh Dump/01007EF00011E000           # game files and game code onto the phone
android/run_boot.sh 120                               # start the game, log to android/out/boot.log
