Illustrative replay of recorded results — figures come from the official compatibility database and our tested configurations, not a live capture.
Overview
The project, the lineage, and the honest state of play — before any numbers.
Not a scam. Not vaporware. A genuinely real, actively developed PS4 emulator for Android.
Bachata S4 is an independent, open-source project by developer JICA98 — a fork of shadPS4, the leading open-source PlayStation 4 emulator originally built for PC and Linux, reworked to run on ARM64 Android devices with an Android-specific frontend and a managed runtime layered on top.
That lineage matters. The Android emulation space has spent years drowning in fake PS4 emulator listings; Bachata S4 is one of the very few projects built on a respected, working emulator core — which immediately separates it from the clickbait. And as of v0.1.9 it moves fast: an offline, signature-verified patch system, FEX-only execution, and flagship hardware reaching genuine 60 FPS territory.
A PS4 is nearly a decade old and most current flagship phones are technically more powerful — the emulator software maturity, not raw hardware, is the remaining bottleneck.

Five layers stand between a PlayStation 4 game and your phone. Tap each one.
PS4 games are compiled for x86-64 processors. Virtually every Android phone runs ARM64 silicon. Getting PS4 software running on a phone therefore requires several cooperating layers — emulation, binary translation, a Linux userland, the graphics stack, and the Android shell itself.
Bachata S4 bundles all of them into a single app. Understanding which layer does what also explains why results scale with your processor generation: translation, memory and graphics load all flow through this stack.
Everything ships in one APK. The emulator core, the managed Linux runtime and — new in v0.1.9 — an offline patch repository, with every patch verified by Ed25519 signature before it loads.
Handles the actual PS4 system emulation: kernel and HLE calls, GPU command processing, and game logic — the proven core originally built for PC and Linux, adapted for the Android runtime.
An x86-64-to-ARM64 dynamic translation layer — PS4 game code is rewritten on the fly to execute on ARM64 phone chips. As of v0.1.9, Box64 is gone entirely: launch is locked to FEX.
A reproducibly built Debian/glibc Linux userland bundled with the app, giving the translated x86-64 code the environment it expects to run in.
All graphics are drawn through Vulkan — the same API the PS4 GPU is programmed against — mapped onto your phone GPU, with per-game settings and the v0.1.9 patch system controlling the load.
The Android-specific frontend: display output, audio, touch controls, physical controller mapping, and app lifecycle management.

Requirements
The floor is Android 12 on ARM64. The practical ceiling is your RAM.
| Requirement | Details |
|---|---|
| Operating system | Android 12 or newer (API 31+) |
| CPU architecture | arm64-v8a only — no 32-bit support |
| Graphics | Vulkan-capable GPU |
| Recommended hardware | Recent flagship Snapdragon processor — Snapdragon 8 Elite shows the best results in our tests, with 8 Gen 3 and 8 Gen 2 close behind |
| RAM (community-reported) | Heavier titles like Bloodborne can use up to ~12GB on high-RAM flagships; phones with only 6–8GB total may struggle on the heaviest titles. Lighter titles need far less. |
| Storage | Varies — app, runtime, shader cache, plus your own game dumps |
| Content | User-owned homebrew or legally dumped PS4 software only |

Compatibility
From the official, evidence-based database — every entry tied to a screenshot and a log.
So many other games are also working — you can check on YouTube for community gameplay and patch setups on almost every popular title. The database below is just the formally verified snapshot.
| Game | Status | Notes |
|---|---|---|
| Bloodborne | IN-GAME | Community focus title — best results with the full v0.1.9 patch set |
| Dark Souls: Remastered | IN-GAME | Runs well with the v0.1.9 patch set applied |
| Sonic Mania | IN-GAME | Near a locked 60 FPS in our tests |
| Sekiro: Shadows Die Twice | IN-GAME | Stable after the initial shader compile; occasional dips |
| Crash Bandicoot N. Sane Trilogy | MENUS | Reaches menus; gameplay pending in a future release |
| Galak-Z | BOOTS | Title screen output; input support pending |
| Additional tested title | IN-GAME | Snapdragon 8 Elite · ~60 FPS (dungeon area) |
| Additional tested title | IN-GAME | Snapdragon 8 Elite · locked 30 FPS (stage area) |
| Additional tested title | BOOTS | Title screen output only |

BLOODBORNE · FULL v0.1.9 PATCH SET · ~12GB RAM IN USE
Bloodborne ran at roughly 58–60 FPS in lighter areas and 30–40 FPS in heavier areas with shader compilation — achieved mainly through the patch system rather than a drastic resolution cut.
BLOODBORNE · SAME PATCH SET · 6–8GB RAM IN USE
Bloodborne held a fairly steady ~30 FPS with the same patch set applied — notable because this is a two-generation-older processor than the Snapdragon 8 Elite.
BLOODBORNE · AGGRESSIVE RESOLUTION PATCH · MID-RANGE TIER
Bloodborne ran at roughly 23–25 FPS using a more aggressive resolution patch — mid-range processors reach in-game status comfortably; smoothness needs the flagship tier.
This is the data we tested. So many other games are also working — you can check on YouTube for community gameplay and patch setups on your exact processor, from flagships down to capable mid-rangers. Performance scales mostly with how aggressively you apply the patch system, not just the chipset.
Fact check
The most-shared claim about Bachata S4, checked against both official and hands-on sources.
THE CLAIM
VERDICT: PARTLY TRUE
The fair one-liner: on a Snapdragon 8 Elite-class processor with the full patch set applied, Bloodborne can genuinely approach 60 FPS in lighter areas — but it is not a locked-60 experience, it costs most of the visual budget, and it eats flagship-level RAM to do it.
Settings
Heavier titles lean on per-game patches for playable framerates. Pick your hardware tier for the suggested starting set — then tune per game.

Flagship path. The tested 58-60 FPS Bloodborne result came from disabling costly effects — no drastic resolution cut. Try the 60+ FPS mode; drop to a 30 lock if frame pacing suffers.

Free, open-source, and actively developed. The Google Play listing is the easiest install path and supports ongoing development; GitHub releases carry source-linked builds with release notes and checksums for those who prefer sideloading or want to verify builds.
FIRST RUN CONFIGURES THE MANAGED LINUX RUNTIME — THE OFFLINE PATCH REPOSITORY IS BUNDLED AND ED25519-VERIFIED INSIDE THE APK.
Because this is a small, early project attached to a popular emulation name, fake listings follow. Clone apps and bogus PS4 emulator APKs riding trending names are a long-standing problem in the Android emulation space.
Setup
Six simple steps. Tick them off as you go — the progress bar keeps score.
You are all set. If something behaves unexpectedly, clear the cache and relaunch once — and when reporting results, include the release version, processor, Android version and a session log.
FAQ
No — it includes zero games or copyrighted console files of any kind. You have to supply your own legally-owned dumps or legitimate homebrew.
It confirms controllable gameplay was reached in a tested configuration — how smooth it runs scales with your processor generation and how you apply the patch system.
Recent flagship Snapdragon processors with Adreno GPUs show the best results in our tests — Snapdragon 8 Elite leads, with 8 Gen 3 and 8 Gen 2 close behind. Capable mid-range chips like the Snapdragon 7+ Gen 2 reach in-game status with a heavier patch set.
Heavier titles like Bloodborne have been recorded using up to ~12GB RAM on flagship configurations. Phones with only 6–8GB total may struggle on the most demanding titles — even if the processor itself is fast enough.
Yes — this is the data we tested, and so many other games are also working. You can check on YouTube for community gameplay and patch setups covering almost every popular title and processor.
Bottom line
Bachata S4 is a genuinely real, actively developed, open-source attempt at PS4 emulation on Android — built on the respected shadPS4 core rather than being a scam or clickbait app, which sets it apart from the wave of fake PS4 emulator listings that have circulated for years. Progress is fast: the v0.1.9 patch system alone took Bloodborne from barely-playable slow motion to genuinely smooth on flagship hardware in a matter of weeks.
It is still an early project — and the best results ask for flagship-tier processors and plenty of RAM. But with an offline verified patch repository, FEX-only execution and a GPU watchdog landing in a single release, the trajectory is unmistakable.
A fast-moving project to watch closely — and on flagship silicon, already one to play.
