Warning

Currently the primary development target is Windows.

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.bin and .elf files
• Executing native CPU instructions
• Reading basic game metadata (title, version, etc.)
• Loading system modules (prx / sys_module)
• Partial support for some kernel functions
• Fiber and AMPR exports
• 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.

Currently the project primarily targets Windows. Cross-platform support (Linux and macOS) is planned, but development is currently focused on Windows to simplify early-stage debugging and iteration.

Using

• Build or Publish project or download in release tab.
• Open Powershell.
  • Run Emulator GUI.
  • Or command: .\SharpEmu "eboot.bin" 2>&1 | Tee-Object -FilePath "log.txt"

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

1. Install the .NET SDK.
2. Clone the repository: git clone https://github.com/par274/sharpemu.git
3. Open the solution file (SharpEmu.slnx) in VSCode.
4. Build the project: dotnet build or dotnet publish
5. Build artifacts will be located in the artifacts directory.

This project does not contain any copyrighted system firmware, game data, or proprietary PlayStation assets.

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.
