With this version the beta program test is now closed. You can download the last build release on the button link below. PCSX2 is written in C/C++ and is designed to make use of instruction caching and a dynamic recompiler scheme to try and achieve better performance while emulating the PS2’s complicated CPU. PCSX2 is a PS2 emulator, a free program that tries to replicate the Play Station 2 console to enable you to play games on your Mac, Win32, Linux, iOS, and Android OS platforms.
