KytyPS4 — PS4 Emulator for Android

A PS4 emulator for Android built on shadPS4 running under Box64, with a Winlator-style embedded X server, Vulkan through Vortek and Mesa Turnip drivers. Kotlin/Compose UI talking to the C++ core and guest runtime through JNI.

Fork From — Bachata S4

ourselves, with special attention to making it work on Android 10

This is a real emulator: it runs actual PS4 games on your phone Android 10-11

the will be ps5 in emu but soon

Repository Policy

Repository Purpose: To safeguard the codebase and maintain proprietary performance enhancements (KytyPS4 Android is closed-source This official) repository does not contain the emulator's source code Instead, it serves as the official version archive and primary distribution platform for releasing APK builds managing compatibility issues and sharing user guides...

Status

From my testing in games like Undertale + sonic mania. It boots and reaches gameplay at roughly 40 to 50 fps on a Snapdragon 855 6 Ram + LSFG Frame Generation — How Its work?

Screenshot - Test

Xeodrifter	Undertale
Balatro ( just start And then crash )	Sonic Mania
silksong	Dead.Cells

And many more...
