Modder Creates Windows OS for Jailbroken PS5

A modder is working on a homebrew project to transform a jailbroken PlayStation 5 into a Windows gaming device. The initiative, led by developer Mihawk, has evolved from a simple translation layer called PS5 Proton into a full operating system dubbed MihawkOS, which draws design inspiration from Windows 11.

The system uses Valve's Proton compatibility layer to enable 32-bit and 64-bit Windows games to run directly on modified PS5 hardware. Previously, playing Windows titles on the console required setting up a complete Linux environment through hypervisor or kernel exploits—a more cumbersome process that MihawkOS aims to simplify.

Mihawk is known for earlier work on PS5 RetroArch, a tool for running classic games on the console. The new project has expanded beyond its initial scope to include native Linux binary support, allowing direct execution of open-source applications alongside Windows software.

Both MihawkOS and PS5 Proton remain in private development with no public release date announced. The developer has not disclosed performance benchmarks for games running on the system, though progress continues at a steady pace. The project reflects a broader surge in PS5 emulation and modding efforts in recent months.
