ChuckStation 5

ChuckStation 5 is an open-source PlayStation 5 emulator backend and compatibility layer written in C++20.

Overview

ChuckStation 5 provides a high-performance guest execution framework for PS5 homebrew and research applications.

Key subsystems:

• CPU Interpreter: x86-64 execution pipeline supporting ALU, vector/SSE stubs, control flow, and syscall traps.
• Syscalls: POSIX/FreeBSD-compatible syscall layer for memory management, process execution, and synchronization.
• Kernel Runtime: Handles guest threads, mutexes, condition variables, events, and virtual memory space.
• Graphics & Display: Modular command-list processor supporting Vulkan, DirectX 12, DirectX 11, and headless backends.
• Audio & Input: Low-latency audio buffer submitter and configurable input mapping.
