We support operating systems that not even Microsoft and Apple themselves support anymore, such as macOS X on PowerPC Macs, and RetroArch being available on Windows OSes as far back as Windows 95.
Over the years, the development changed hands several times with PCSX-Reloaded now being the main version. RetroArch can run on the usual platforms like Windows, Mac OS X and Linux, but it stands alone in that it can support far more platforms beyond just that. PCSX is a free and open-source console emulator which allows software designed to be used with the PlayStation to run on personal computer.
