Its repository describes a relinker that converts executables to the target system’s native format, alongside implementations of system PRX libraries for dynamic linking. The project says it uses neither emulation nor a separate runtime process.
The repository’s compatibility evidence is limited: it lists Dreaming Sarah, a 2D platformer, as running at a stable 60 fps on a GTX 1050 Ti and an i5-7500. It also says unsupported or unexpected states throw an error and terminate the process. This is evidence of a tested example, not general PS5 game compatibility.
The project says it does not include or distribute copyrighted software, firmware, cryptographic keys, or proprietary libraries. Users are responsible for obtaining and using binaries lawfully. Source: https://github.com/boykopovar/AnyPS5
