I turned my PS4 into a Steam Machine with CachyOS!

A step-by-step walkthrough of installing CachyOS Linux on a jailbroken PS4 to create a DIY Steam Machine. The process covers exploiting the PS4 firmware, identifying the Southbridge chip type, preparing an external SSD with FAT32, loading a Linux kernel payload via GoldHen, and completing the install via a rescue shell script. Once booted into the CachyOS desktop, Steam is installed and various games are tested: native Linux titles like SuperTuxKart run smoothly, GameCube emulation via Dolphin hits 40-55 FPS, Wii emulation struggles at 15-30 FPS, and indie Steam games run well. AAA titles like Marvel's Spider-Man crash the system. The result is a functional but limited Linux desktop capable of light gaming and basic web browsing.
