Add the KB-RPCS3 visual identity built on the original stylised numeral-3 mark: a transparent logo, a square app icon, a wide README banner, a 2:1 GitHub social-preview image and release artwork. The SVGs are the editable source of truth; render.py reproduces every PNG. None of the artwork derives from Sony, PlayStation or upstream RPCS3 branding.
KB-RPCS3
An unofficial port of the RPCS3 PlayStation 3 emulator to jailbroken PS5 consoles.
| Version | Alpha 0.1.0 (2026-10-09) |
| Maintainer | KB |
| PS5 title ID | PPSA99303 |
| This release | source code only — no PS5 binary yet (why) |
KB-RPCS3 runs RPCS3, the open-source PlayStation 3 emulator, as a native PS5 homebrew title with its own home screen, settings and game installer. It uses RPCS3's emulator core through a Vulkan driver (RADV) running directly on the console.
Unofficial. KB-RPCS3 is not made, endorsed or supported by the RPCS3 project or by Sony Interactive Entertainment. Please do not ask the RPCS3 team for help with it. "PlayStation", "PS3" and "PS5" are trade marks of Sony Interactive Entertainment Inc.
Status of Alpha 0.1.0
There is no downloadable PS5 package yet. The PS5 title links RPCS3's GPL-2.0-only core with GPL-3.0 PS5 components, and those licences cannot be combined in one distributed program. Permission from the authors of the PS5 components is being sought; see LICENSING_STATUS.md. Until then this release contains the source code and build instructions only.
What was tested on a real console (one PS5 Slim, firmware 13.60, etaHEN, kstuff lite, ShadowMountPlus) with the development build this release is based on:
| Game | Result |
|---|---|
| LIMBO | playable: picture, sound and controls |
| WWE 12 | playable, with slowdowns during heavy moments |
| Grand Theft Auto IV | playable; roughly 13–27 FPS when driving at normal game speed (the game's own cap is 30) |
Other games have not been tested. See COMPATIBILITY.md and KNOWN_ISSUES.md.
Not yet tested on a console: the exact Alpha 0.1.0 source (it adds logging and off-by-default experimental options on top of the tested build) and the KB-RPCS3 branding.
