Developed by the creators of the famous PS3 emulator (RPCS3), this is a research-focused Linux project. Summary of Safety Tips
Emulating the PS4 is incredibly complex. While the PS4 uses an x86-64 architecture (similar to PCs), its custom OS and GPU hardware are difficult to replicate. Legitimate progress is being made, but it is not yet at a "download and play" stage for the general public.
The "PCSX4" project is a long-standing hoax. Real emulation projects are typically open-source and hosted on platforms like GitHub; PCSX4 uses a polished, professional-looking website to trick users into downloading "installers" that require "verification keys" obtained through malicious links.
Currently the most promising project, having recently made headlines for being able to boot and run parts of Bloodborne .
If you are interested in the actual progress of PS4 emulation, follow these credible, open-source projects. None of these are currently capable of running major AAA games at full speed, but they are the only real efforts:
