PCSXR
PCSXR is a free, open-source PlayStation 1 emulator for macOS that allows users to play PS1 games on modern Macs by loading disc images and optionally providing a BIOS file. It supports game saves, memory cards, controller input (including Bluetooth gamepads), and plugin-based graphics and audio backends that allow enhanced rendering beyond the original console's capabilities. PCSXR is widely used by retro gaming enthusiasts who want to replay classic PS1 titles on their Macs with improved visuals.
AI Recommendation
1 suggestionPCSXR has not been updated since 2013 and exists only as a 32-bit Intel build with no native Apple Silicon support. The project appears abandoned — the CodePlex repository where it was hosted has since been shut down by Microsoft, and there is no evidence of ongoing development or maintenance. The emulator will stop running entirely when Apple removes Rosetta 2 in macOS 28 (September 2028). If you rely on PCSXR for PS1 emulation, you should migrate to PCSX2 (which emulates PS2 games and includes a native Apple Silicon build available through the official PCSX2 website) or DuckStation, a newer PS1 emulator that ships with a native Apple Silicon version and offers significantly improved compatibility and graphics quality compared to PCSXR. Both modern alternatives are free and open-source, and both will continue to work after Rosetta 2 is removed.
