* [Core] Add POSIX native execution and PS5 SELF support Extend the native backend, guest TLS, fixed-address memory, and loader paths needed by PS5 titles on Windows, Linux, and macOS. Keep workstation GC so high-core-count hosts do not reserve over fixed guest image bases. * [HLE] Expand PS5 service and media compatibility Add the kernel, threading, save-data, networking, audio, video-codec, font, dialog, and service exports required by newer PS5 software. Preserve every SysAbi NID currently registered by main while adding the compatibility surface used by ASTRO BOT. * [AGC/Vulkan] Extend Gen5 shader and presentation support Expand PM4 handling, Gen5 shader translation, MRT and packed export support, guest image tracking, depth initialization, texture aliasing, and Vulkan presentation. Add the performance overlay and address-filtered diagnostics used to validate ASTRO BOT with original shaders. * [Core] Align static TLS reservation across hosts * [Pad] Align primary user ID with UserService * [Gpu] Preserve runtime scalar buffers across renderer seam * [AGC] Restore omitted command helper exports * [Vulkan] Reuse primary views for promoted MRT targets * [Vulkan] Preserve scratch storage bindings in compute dispatches
SharpEmu
An experimental PlayStation 5 emulator for Windows, Linux and macOS.
Join our Discord for development updates, compatibility discussions, support, and community chat.
Note
SharpEmu supports Windows x64, Linux x64, and macOS x64. Apple Silicon Macs can run the macOS x64 build through Rosetta 2.
Warning
SharpEmu is an experimental PS5 emulator developed from scratch in C#. The current focus is on accuracy and infrastructure setup rather than game-specific compatibility.
Info
SharpEmu is an emulator project currently in its early stages of development.
This project is developed purely for research and educational purposes. There are no commercial goals associated with it. We enjoy learning about system architecture and reverse engineering.
SharpEmu focuses exclusively on the PlayStation 5.
Our goal is not to emulate PS4 games, as there is already an excellent emulator dedicated to that platform: ShadPS4.
Status
The emulator can currently load the eboot.bin of real games, execute native CPU instructions, and partially handle kernel-related functionality. However, several critical components are still missing.
Current capabilities include:
- Loading
eboot.binand.elffiles - Executing native CPU instructions
- Reading basic game metadata (title, version, etc.)
- Loading system modules (
prx/sys_module) - Partial support for some kernel functions
FiberandAMPRexports- PlayGo scenarios
- Initial loading game files
- Shader/resource submits and AGC initial
- Video outputs in some games
Some games have reached like sceVideoOut and AGC stages.
SharpEmu supports Windows, Linux, and macOS hosts. Video output uses Vulkan on Windows and Linux, and MoltenVK on macOS. Platform support is still experimental, so compatibility and performance vary by game, operating system, and GPU driver.
Using
Download the release archive for your operating system, extract it, and launch
SharpEmu with the path to a legally obtained game's eboot.bin.
Windows PowerShell:
.\SharpEmu.exe "C:\path\to\game\eboot.bin" 2>&1 |
Tee-Object -FilePath "SharpEmu.log"
Linux and macOS:
chmod +x ./SharpEmu
./SharpEmu "/path/to/game/eboot.bin" 2>&1 |
tee SharpEmu.log
A Vulkan-capable GPU and current graphics driver are required. The macOS release includes the MoltenVK Vulkan implementation.
Games Tested

Important
This project does not support or condone piracy.
All games used during development and testing are dumped from consoles that we personally own.
Users are expected to use legally obtained copies of their games.
Build
- Install the .NET SDK version specified in
global.json. - Clone the repository:
git clone https://github.com/sharpemu/sharpemu.git - Open the solution file (
SharpEmu.slnx) in VSCode. - Build the project:
dotnet buildordotnet publish - Build artifacts will be located in the
artifactsdirectory.
Disclaimer

Special Thanks
The following projects were extremely helpful during development:
-
ShadPS4
Helped with understanding the basic architecture of the PlayStation 4. -
Kyty
One of the few PS5 emulator projects available and very useful for studying native code execution. -
Ryujinx
Provided valuable references for filesystem handling and low-level C# implementation patterns.
