PCSX2 is a free and open-source PlayStation 2 (PS2) emulator. Its purpose is to emulate the PS2's hardware, using a combination of MIPS CPU Interpreters, Recompilers and a Virtual Machine which manages hardware states and PS2 system memory. This allows you to play PS2 games on your PC, with many additional features and benefits. RetroAchievements are enabled by default, to disable this functionality, pass ACHIEVEMENTS=OFF to the build script. Discord Rich Presence is disabled by default, to enable Discord functionality, pass DISCORD=ON to the build script.
