Prospero-win runs Windows games on a jailbroken PS5 through its own port of Wine

The first packaged release plays Half-Life 2 at 60 frames per second and GTA IV at around 50, on the console itself. It needs a PS5 that already runs homebrew, and it leaves DRM and anti-cheat alone.

A new homebrew app called prospero-win runs Windows games on a jailbroken PlayStation 5, on the console itself and with no PC streaming to it. Its developer, Manuel Alejandro Pereira Esaa, published the first ready-made build, v0.1.0, on 5 October. You copy one folder to the console and a launcher appears on the PS5 home screen.

It is not an emulator of a whole PC. It is a port of Wine, the open source layer that lets Windows programs run on other systems. The release notes say the app carries its own copy of Wine, “so there is no PC streaming involved: the game runs on the console.”

How it works

The PS5 has an x86-64 processor, the same family as a desktop PC, so 64-bit Windows programs run on it directly. Most of the older games people will try first are 32-bit, and for those the project has its own translator that turns 32-bit code into 64-bit code as the game runs. The project's benchmark notes estimate that translator at 85 to 93% of the console's native speed in a 7-Zip test.

Direct3D 8, 9, 10 and 11 games draw through DXVK and Vulkan, using the open source RADV driver from Mesa. Older OpenGL games are supported, and so are 2D programs that draw with GDI. Direct3D 12 is not on the list.

The DualSense shows up to games as an Xbox-style controller with rumble, and it can be mapped to keys for games made for keyboard and mouse. A USB keyboard and mouse work too.

What runs today

The release lists these as working, measured on one PS5 on firmware 12.02 at 1080p and 60Hz:

Half-Life 2 at 60 frames per second on High settings.
GTA IV in its Complete Edition at about 45 to 55 in the open city, dropping to the mid-40s in gunfights and crowds, after a load of about 90 seconds.
GTA San Andreas (PC 1.0) at 60, including with a handful of mods.
Half-Life, Counter-Strike 1.6 and OpenArena through OpenGL, with keyboard and mouse.
Warcraft III (Reign of Chaos 1.27a), cinematics and sound included.
Space Cadet Pinball and Wine's own Minesweeper.

Those are the developer's own figures from a single console. There are videos on the developer's channel to back them, and they are moving quickly: the GTA IV video from 4 October gave 30 to 40 frames per second in Liberty City and promised more translator work within days. The release notes a day later say 45 to 55.

The catches

You need a PS5 that can already run homebrew, with an FTP server, an ELF loader and an app loader on it. You also need a Linux PC, or a virtual machine or WSL, because games are installed there first and then copied across. The console side runs one program at a time, so installers and games that must start from a separate launcher do not work on it.

You need your own copies of the games. None are included, and the app leaves copy protection alone. The release notes are blunt about DRM and anti-cheat: “prospero-win doesn't bypass either, so games that need them won't run.” The project page adds that support for 32-bit and 64-bit software “does not yet mean every modern Windows game works.”

There are smaller limits too. There is no support for 16-bit Windows or DOS programs and no mouse wheel yet, and games that play their intro movies through DirectShow need LAV Filters installed or they can hang on the first one.

On firmware, the developer says testing was done on 12.02 and that the app itself does not depend on a firmware version. The parts that do are the jailbreak, the loader and a small helper bundled with the app.

Open source, and partly AI-written

The code is under the LGPL 2.1, the same licence as Wine. The release notes end with a “Generated with Claude Code” credit and a number of commits in the repository credit Claude as well, so at least some of the project was written with an AI coding tool.

The roadmap lists a wider set of Direct3D games, more OpenGL games, DirectInput controllers and speed as what comes next. For now the developer's own summary is the fair one: “It's experimental. Some games work well, and many haven't been tried yet.”
