What comes after Delta? Prosperity.

Prosperity, originally launched as PS4Delta in 2019, is a PlayStation 4 and PlayStation 5 emulator for Linux and Android. Windows support is planned for a later release.

On AMD64 hosts, the CPU runs without emulation. On ARM hosts, FEX is used to execute the CPU code.

The GPU is fully emulated, with graphics code recompiled to SPIR-V.

Everything else, including the loader, kernel HLE, and devices, runs as natively on the host as possible. Graphics output is handled through Vulkan and SDL3.

Documentation

• Building
• 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+, and a minimum of 6-8 GB vram (the more, the better).

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.
