Bachata S4+ 0.2.1 is available for experimental PS4 emulation
Bachata S4+ version 0.2.1 was published on September 19, 2026, as an Android APK for ARM64 devices. The update fixes the Documents Provider, includes stability changes and adds performance patches for The Last of Us Remastered.
The project is an experimental PlayStation 4 emulator for Android. It is an independent community modification based on Bachata S4, with additional work covering compatibility, controller support, Android interface behavior, execution backends and game-specific fixes.
The Last of Us Remastered receives targeted performance work
The most notable game-specific change in this build is the addition of performance patches for The Last of Us Remastered. These are targeted changes rather than a general performance guarantee for every PlayStation 4 title. The project’s broader compatibility results can vary by device, graphics driver, Android version, game version, configuration and selected execution backend.
Bachata S4+ includes experimental work with FEX and Box64 for running x86 or x86-64 software on ARM64 hardware. Those backends can behave differently between games and devices, so a patch aimed at one title should not be treated as evidence that the same result applies elsewhere. The project also works on per-game configuration so that compatibility changes can be isolated where possible.
File access and stability fixes
Version 0.2.1 fixes the Android Documents Provider. The release notes do not provide further technical details about the original failure or identify the particular file workflows affected by the fix.
The build also includes unspecified stability fixes. No individual crashes, freezes or regressions are listed, so the practical scope of those changes cannot be narrowed further from the published notes.
What Bachata S4+ provides
Bachata S4+ is intended for experimental PlayStation 4 emulation on ARM64 Android hardware; it is not an emulator running on the original console. Its development priorities include compatibility research, physical and touch controller support, Vulkan-related work, memory behavior, GPU synchronization and diagnostic tooling.
The project’s compatibility documentation warns that games may reach gameplay with graphical or performance problems, fail before gameplay, freeze, crash, render incorrectly or experience audio and input issues. A title reaching gameplay does not necessarily mean it is fully playable from beginning to end, and compatibility may change between builds. Results can also differ substantially across SoCs, GPUs, RAM configurations, Android versions, drivers, thermal limits and emulator settings.
Independent community project
Bachata S4+ is an independent community project and is not an official Bachata S4 release. The README identifies its historical starting point as Android binary releases of Bachata S4, with the main historical base associated with Bachata S4 0.1.8. It describes Bachata S4+ as an independent modification and compatibility research project rather than a conventional source-code fork of that release.
The project is also separate from shadPS4, FEX-Emu, Box64 and onRps4-Android. Those projects are presented as technical lineage, runtime technology or research references rather than as official affiliations or endorsements.
Release details
The 0.2.1 release was published at 02:54:10 UTC on September 19, 2026. Its Android package is named Bachata-S4-Plus-v0.2.1.apk. The published release notes list the Documents Provider fix, stability fixes and The Last of Us Remastered performance patches as the changes in this build.
Bachata S4+ does not distribute PlayStation 4 games, console firmware, system files, decryption keys or other copyrighted game data. Users must provide and use any required software legally.
