While initially only supporting Microsoft Windows and Android, this quickly grew to include Blackberry 10, Symbian, macOS, Linux and later iOS. Since its inception, PPSSPP has had a focus on portability with support for multiple architectures and operating systems. PPSSPP also supports the Vulkan API, which was added in v1.5.4 release and is intended to provide a substantial performance boost on supported devices. All ports of PPSSPP for mobile devices support the use of accelerometers, keyboards and gamepads as input devices. The ports of PPSSPP for mobile devices offer additional features specific to each platform, such as 'immersive mode' for Android devices, support of the multimedia buttons within Symbian devices and screen stretching on BlackBerry 10 devices to support square screens. PPSSPP offers graphical features that are enhancements over the PSP's capabilities, such as higher screen resolutions, antialiasing, image scaling, support for shaders, and linear and anisotropic filtering. To decode PSP multimedia data PPSSPP uses the FFmpeg software library, which was enhanced to enable it to handle Sony's proprietary ATRAC3plus audio format as used by the PSP. PPSSPP supports save states, dynamic recompilation ( JIT) and has rudimentary support of ad hoc wireless networking.
