Unicorn Overlord PC: rehosting the PS4 game on Linux and Windows

Unicorn Overlord PC runs the PlayStation 4 Unicorn Overlord executable on Linux and Windows through a game-specific loader and host runtime. It adjusts executable addresses, implements imported PS4 system functions and routes GPU commands through a shadPS4-derived Vulkan layer. The author reports playing through the prologue and first chapter battle, with saving and loading working.
