Prosperity
Prosperity, formerly PS4Delta, is a PlayStation 4 and PlayStation 5 emulator. The README says CPU code runs directly on AMD64 or through FEX on ARM64, and that PS4 and PS5 graphics are translated to SPIR-V. It ships no Sony code. You must supply your own system modules and games. This site does not explain how to produce those modules.
Unofficial notes. No game files, BIOS, firmware, keys, ROMs, or mirrored builds. Download each project only from its official GitHub repository.

What is cited
The README we checked does not publish a numbered compatibility table. pcgaming.io on 10 Oct 2026 described showcase gameplay for the PS5 versions of Dead Cells, The Binding of Isaac, and Minecraft. Treat that as a press summary of the project's own demos, not as a list we retested.
There is no Windows download on the v0.0.1 release. Building from source uses the repository's Nix or CMake instructions. A site offering a Windows Prosperity EXE with a BIOS pack is not this repository.
Install from the official release
Stay on Linux or Android
Download https://github.com/Force67/prosperity/releases/tag/v0.0.1 if you want the Ubuntu package, or clone the repository to build. Do not hunt a Windows port that the project still marks as planned.
Read the upstream install notes
The repository documents system modules and CLI flags. Follow that document. This page will not restate a dump or decryption procedure.
Expect a small showcase, not a catalog
Until Prosperity publishes its own compatibility database, do not treat a three-title press note as coverage of retail PS5 games.
