A compatibility update for ARM64 Android
Bachata S4+ version 0.2.4 is a new Android build for experimental PlayStation 4 emulation on ARM64 devices. Published on October 2, 2026, the update moves the project to the Bachata S4 0.2.4 core, with compatibility improvements covering many games.
The release includes an APK named Bachata-S4-Plus-v0.2.4.apk. Bachata S4+ is an independent community project rather than an official Bachata S4 release, and it is not affiliated with Sony Interactive Entertainment or the original Bachata S4 developers.
Game-specific fixes and control changes
Marvel’s Spider-Man receives a dedicated fix in this build. The notes do not specify the exact problem addressed, but the change targets the game directly alongside the updated emulator core.
The release also improves the control workaround for inFAMOUS Second Son and adds a control-support workaround for inFAMOUS First Light. These changes target input behavior, giving users of those titles updated control handling to test on Android.
As with other experimental PS4 emulation projects, reaching gameplay does not guarantee complete playability. Results can vary with the Android device, system-on-chip, GPU, Vulkan driver, game version, emulator settings and selected execution backend.
Performance patches and PKG folder support
Version 0.2.4 adds new performance patches and corrects existing ones. The release notes do not identify the affected games or provide benchmark figures, so the practical impact may differ between titles and devices. These patches form part of the project’s broader effort to improve compatibility without applying every change globally.
The update also adds support for importing PKG files into a custom folder and running games directly from that location. This gives users another way to organize supported game files for use with the emulator. The release information does not provide further details about folder selection or file-management options.
What Bachata S4+ is designed to do
Bachata S4+ is an experimental PlayStation 4 emulator for ARM64 Android devices. The Android device is the host platform; the software is intended to emulate PlayStation 4 software rather than turn Android into an official PlayStation system.
The project focuses on compatibility research, controller support, Android interface changes and game-specific workarounds. Its documented technical work includes FEX as an x86 and x86-64 execution layer on ARM64, along with experimental Box64 integration. The project also investigates Vulkan behavior, GPU synchronization, memory compatibility and per-game configuration.
FEX and Box64 can behave differently depending on the game and device, and Box64 remains experimental. A title that works with one execution backend or graphics driver may not behave the same way with another.
A project still under experimentation
Bachata S4+ began from Android binary releases of Bachata S4 and has received independent modifications, compatibility research, runtime experiments, controller improvements and Android-specific changes. The project identifies its historical starting point as Bachata S4 0.1.8, while noting that the complete emulator source corresponding to that APK was not available in the associated public source archive.
The project’s compatibility goals include improving games without breaking working titles, isolating game-specific fixes and making changes easier to reproduce and compare. Its documentation also highlights the importance of testing across different hardware, Android versions, graphics drivers and emulator configurations.
Users should therefore treat 0.2.4 as an experimental public build. The documented release changes are concentrated on the updated core, compatibility, performance patches, PKG-folder support and controls for the listed games; no broader compatibility list or performance measurements are provided in the release notes.
Legal use and project boundaries
Bachata S4+ does not distribute PlayStation 4 games, console firmware, system files, decryption keys or other copyrighted game content. Users are responsible for obtaining and using software legally.
The project is distributed under GPL-2.0-or-later for its original code, while third-party components remain under their respective licenses. It is not an official release of Bachata S4, shadPS4, FEX-Emu, Box64 or onRps4-Android.
