SharpEmu.Tools.ShaderDump feeds hand-assembled Gen5 (gfx10) instruction words — cross-checked against LLVM's AMDGPU target definitions — through the real Gen5ShaderTranslator -> Gen5SpirvTranslator pipeline via reflection (no emulator source changes; the project is not in the main solution) and dumps the resulting vertex/compute SPIR-V blobs for inspection with spirv-val / spirv-dis. Each bundled program carries an expectation: fmac/muls/sopp-hints/exec must decode and emit both stages, while sopp-mode (s_round_mode, s_denorm_mode) pins the loud unknown-sopp decode failure those FP MODE writes must keep producing until their semantics are modeled (#108). Any unexpected outcome makes the tool exit non-zero, so it can gate scripts or CI. The exec program computes real ALU results and stores them with buffer_store_dword, toggling EXEC off and on around a pair of stores; its exec-cs.spv blob is designed for numeric verification on a real Vulkan device (follow-up tool). All dumped blobs pass spirv-val --target-env vulkan1.3. Co-authored-by: Claude Fable 5 <noreply@anthropic.com>
SharpEmu
An experimental PlayStation 5 emulator for Windows, Linux and macOS.
Join our Discord for development updates, compatibility discussions, support, and community chat.
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.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.
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
-

- Demon's Souls [PPSA01341]
- Demon's Souls is now video loop. Shaders are ready to be converted to SPIR-V/Vulkan. We are continuing our work on this.

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.
- Clone the repository:
git clone https://github.com/par274/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
SharpEmu is an experimental emulator intended for research and educational purposes.
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.
