KB-RPCS3 
 Unofficial RPCS3 Port for PlayStation 5. 
KB-RPCS3 runs RPCS3, the open-source PlayStation 3 emulator, as a
**native PS5 homebrew title**. Its Mesa/RADV Vulkan renderer talks to the console
directly, RPCS3's emulator core does the PlayStation 3 work, and a PS5-native shell
provides the home screen, per-game settings and installers.
> **Alpha 0.1.0 is a source release.** There is **no downloadable PS5 package yet** —
> the title's licence mix is unresolved, so a binary cannot be distributed. The
> source, the RPCS3 patch series and the build instructions are public. See
> Licensing status.
> **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

## Status of Alpha 0.1.0
KB-RPCS3 is an **early alpha**. This release publishes what exists — a working
development build's source and a tested port — and is explicit about what has not
been done yet.
- **No PS5 binary is distributed.** The title links RPCS3's **GPL-2.0-only** core with
 **GPL-3.0** PS5 components; those licences cannot be combined in one distributed
 program. The current combined executable has an **unresolved GPL compatibility
 issue** and has **not passed final PS5 testing**.
- **The exact Alpha 0.1.0 source has not finished console regression testing.** Games
 were verified with the development build this release is based on; Alpha 0.1.0 adds
 speed/timing logging and off-by-default experimental options on top of that build.
- **No performance improvement is claimed.** The experimental SPU options are off by
 default and have not been measured at normal game speed.
## Features
- **RPCS3 on the console** — the emulator core built for the PS5, rendering through
 Mesa/RADV Vulkan directly on the hardware.
- **Native home screen** (`PPSA99303`) with **Games**, **Install**, **Settings** and
 **System** tabs.
- **Global and per-game settings**, with recommended settings pulled from RPCS3's
 public configuration database when it is available.
- **Installers** for PS3 firmware (`PS3UPDAT.PUP`), PSN packages (`.pkg`) and licences
 (`.rap`).
- **PS5 home-screen tiles** that launch a game directly.
- **DualSense** contro
