PCSX2 is a PlayStation 2 emulator originally created for the Windows operating system. Over time, ports of PCSX2 for other platforms have emerged, including one for Mac OS X. Called PCSX2/Mac, it is not as well updated and functional as the Windows version, but is capable of playing many PS2 games without problems. In order to run properly, PCSX2 requires that a particular set of plug-ins and other tools, including a BIOS file, be installed.
