PCSX is a free and open-source, video game console emulator that allows software designed to be used with the Sony PlayStation to run on personal computers.

[6] PCSX has a high compatibility rate,[7] and is currently available for a number of different operating systems including, Microsoft Windows, macOS, and Linux.

PCSX-df was created in 2006 and added new features, a new GTK-based interface, AMD64 support, and corrected some bugs, but was developed mainly with only Linux compatibility in mind.

Additionally, the plugin system will be replaced through a single monolithic codebase that handles all aspects of the PlayStation emulation.

Linux, macOS/OS X, and Microsoft Windows on x86-based computers are the main development focus of PCSX-Reloaded but various PCSX iterations have been ported to other platforms as well, including Dreamcast,[11] GameCube,[12] PlayStation 3,[13] Wii,[14] Xbox,[15] and various ARM-based platforms (PCSX-Rearmed fork)[16] such as BlackBerry Playbook and Nintendo 3DS.
