Prosperity

What comes after Delta? Prosperity.

An experimental PlayStation 4 emulator for Linux and Android. Guest x86-64 code runs directly on x86-64 hosts and through an embedded FEX JIT on aarch64 (arm64) hosts; everything else (loader, kernel HLE, devices) is host-native. Graphics are presented with Vulkan + SDL3.

• Installation & running

Quick start (Linux)

Prosperity builds inside a Nix dev shell that pins the exact Vulkan / SDL3 / shaderc toolchain it needs:

git clone --recursive https://github.com/Force67/prosperity.git
cd prosperity
nix develop --command bash -c 'cmake -G Ninja -B build -DCMAKE_BUILD_TYPE=Release && cmake --build build'
./build/delta/main/ps4delta /path/to/game.pkg

See docs/building.md for the non-Nix build, Android, and the available CMake options.

Requirements

On linux

• Processor: x86-64 (made in the last 10 years) with AVX, SSE4.2 and BMI1, or an aarch64 host.
• RAM: 16 GB of RAM (8 may work, depending on the type of game you want to run).
• Graphics: a GPU with support for Vulkan 1.4+.

On android

• Processor: Preferably something new, like one of those fancy new Snapdragons.
• RAM: 12 GB of RAM (8 may work, depending on the type of game you want to run).
• Graphics: a GPU with support for Vulkan 1.4+.

Legal

Prosperity ships no Sony code. You must supply your own decrypted system modules and games, dumped from hardware you own. See docs/installation.md.
