      PCSX2 is an open-source PlayStation 2 (AKA PS2) emulator. Its purpose is
      to emulate the PS2 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.
