Experimental PlayStation 4 emulation for ARM64 Android devices.
Powered by shadPS4,
FEX, a managed Linux runtime, and Vulkan.

This is the Bachata S4 release repository. It hosts releases, compatibility information, documentation, and community coordination; it is not the maintained emulator core source repository.
The maintained emulator core fork has moved to
zenithblue-oss/shadps4-arm64.
Core source development and contributions belong in that repository.

Important
Bachata S4 is experimental software.
Compatibility and performance can vary significantly by game, emulator release, device, Android version, thermal state, and selected graphics driver. A game reaching gameplay on one configuration does not guarantee that it will work on another.
Bachata S4 does not distribute games, firmware, decryption keys, licenses, or other copyrighted console files. You must provide and use only software and content that you legally own or are otherwise legally entitled to use.
Bachata S4 adapts the shadPS4 emulator for modern ARM64 Android devices. It combines:
- the shadPS4 emulator core;
- FEX-based x86-64 guest execution on ARM64 hardware;
- a reproducibly built, managed Debian/glibc runtime;
- Android display, audio, input, and lifecycle integration;
- Vulkan rendering through a compatible system driver, Mesa Turnip, or another explicitly selected custom driver;
- a mobile game library, per-game settings, touch controls, and physical-controller support.
The Android frontend is located in android/BachataS4.
Runtime inputs and pinned upstream revisions are maintained under
runtime/locks.
Compatibility is evidence-based and specific to the exact emulator release, device, GPU, Android version, guest backend, and graphics driver used by the tester.
The live source of truth is the
Bachata S4 compatibility website.
Structured report data, screenshots, and compressed logs are maintained separately in
JICA98/Bachata-S4-Compatibility.

Note
In-game does not mean fully playable. It means controllable gameplay was reached in at least one recorded configuration. Completion, long-session stability, correct rendering, audio, input, and performance may still have major problems. FPS values above describe specific recorded tests and are not performance guarantees for other devices.

Compatibility can differ substantially between devices that appear similar. Check reports from the same SoC, GPU generation, Android version, and driver family whenever possible.
The supported Google Play build is the easiest installation path and directly supports continued development, device testing, and compatibility work.
Install Bachata S4 from Google Play
Source-linked project builds, release notes, checksums, and downloadable artifacts are available under GitHub Releases.
Note
The GitHub download badge counts GitHub release assets only. It does not include Google Play installations.
- Install Bachata S4 from Google Play or a trusted project release.
- Open the app and complete the initial runtime setup.
- Select the graphics driver appropriate for the device.
- Import user-owned homebrew or a legally dumped title.
- Launch the title and allow initial shader or pipeline compilation to complete.
- Compare the result with the live compatibility database.
- When reporting a problem, include the Bachata S4 release, phone, Android version, selected driver, reproduction steps, and sanitized session log.
Bachata S4 does not provide PS4 games, firmware, licenses, decryption keys, or copyrighted system files.
Turnip drivers are not bundled inside the APK. They are installed after application setup from the project’s trusted driver feed or imported from a local compatible ZIP.
The exact driver name, version, build, and source must be recorded in compatibility reports. A filename, Vulkan API version, Android version, or GPU model is not a substitute for the actual Turnip version.
See documents/android-building.md for the maintained
runtime and packaging rules.
The website frontend remains in this repository, while compatibility evidence is stored in the dedicated data repository:

The homepage loads a compact generated index grouped by CUSA ID. Full history is loaded only when a user opens a title, preventing duplicate cards and keeping the site responsive as reports grow.
Use
.agents/skills/bachata-compatibility/SKILL.md
for the complete agent workflow.
The workflow:
- Searches for or creates one canonical game issue in
JICA98/Bachata-S4. - Creates a dedicated branch and Git worktree for
Bachata-S4-Compatibility. - Selects the exact ADB device, Bachata release, and graphics driver.
- Launches the title and captures screenshots, logs, device data, and performance evidence.
- Adds a new immutable report without overwriting previous results.
- Shows the proposed report and screenshots to the tester.
- Publishes the compatibility pull request only after explicit tester confirmation.
- Updates the canonical main-repository issue and embeds representative screenshots in the issue conversation.
A useful report includes:
- official Bachata S4 release tag and exact commit;
- CUSA serial and game/update version;
- exact phone model, SoC, GPU, RAM, and Android version;
- guest backend;
- graphics-driver type, exact version, build, and source;
- the furthest status actually observed;
- clear reproduction notes and known problems;
- representative screenshots;
- sanitized compressed session logs;
- FPS measurements only when the sampling method is recorded.

Bachata S4 is not a finished or universal PS4 emulator. A title may:
- fail before rendering;
- reach only menus or partial gameplay;
- have missing graphics, audio, or input;
- run slowly on current mobile hardware;
- behave differently across Android versions or drivers;
- regress or improve between emulator releases;
- require game-specific emulator work.
Public compatibility testing helps determine whether a blocker belongs to guest execution, kernel/HLE behavior, graphics, audio, input, runtime packaging, or Android integration.

Before opening a new game discussion, search for its exact CUSA ID. One canonical issue is used per game so that reports from different releases, phones, and drivers remain in one conversation.
No. Bachata S4 includes no games or copyrighted console content. Users must provide software they legally own or open-source homebrew.
No. It means controllable gameplay was reached in a specific recorded environment. Check the report’s notes, screenshots, device, driver, and emulator release.
CPU generation, GPU, Android version, available memory, graphics driver, thermal limits, and emulator release can all affect behavior.
Recent flagship Snapdragon devices with Adreno GPUs are currently the most practical testing targets, but no device guarantees compatibility.
Google Play is the recommended supported installation. GitHub Releases provide source-linked project builds and checksums.
