In plain English

RPCS3 is the world's first free and open-source emulator for the PlayStation 3 console. An emulator is software that recreates a gaming console's hardware in code, allowing you to run games designed for that console on a regular PC. RPCS3 specifically emulates the PS3's unusual Cell processor and RSX GPU, which were complex enough that running the console's game library on a PC was considered extremely difficult for many years. The project is written in C++ and runs on Windows, Linux, macOS, and FreeBSD. It uses LLVM for dynamic recompilation, a technique that translates the PS3's CPU instructions into ones your computer can execute at near-native speed. Compatibility varies by game, the project maintains a public wiki with game-by-game status reports. Users can also contribute by testing games and filing bug reports. You would use RPCS3 if you want to play PS3 games on your computer, either because you own the games and want better performance and resolution than the original hardware, or to preserve access to titles. It is licensed primarily under GNU GPL-2.0. Running commercial game discs requires a PS3 system software file and game files you must provide yourself, the project does not include game content.
