Status

Important

shadPS4 is early in development, don't expect a flawless experience.

Currently, the emulator successfully runs small games like Sonic Mania, Undertale and it can even run Bloodborne.

Why

This project began as a fun project. Given our limited free time, it may take some time before shadPS4 can run more complex games, but we're committed to making small, regular updates.

Building

Windows

Check the build instructions for Windows.

Linux

Contributors

Special Thanks

A few noteworthy teams/projects who've helped us along the way are:

• Panda3DS: A multiplatform 3DS emulator from our co-author wheremyfoodat. They have been incredibly helpful in understanding and solving problems that came up from natively executing the x64 code of PS4 binaries

• fpPS4: The fpPS4 team has assisted massively with understanding some of the more complex parts of the PS4 operating system and libraries, by helping with reverse engineering work and research.

• yuzu: Our shader compiler has been designed with yuzu's Hades compiler as a blueprint. This allowed us to focus on the challenges of emulating a modern AMD GPU while having a high-quality optimizing shader compiler implementation as a base.

• hydra: A multisystem, multiplatform emulator (chip-8, GB, NES, N64) from Paris.
