DuckStation - PlayStation (PSX) Emulator

Features

• CPU Recompiler/JIT (x86-64 and AArch64)
• Hardware (D3D11 and OpenGL) and software rendering
• Upscaling and true colour (24-bit) in hardware renderers
• "Fast boot" for skipping BIOS splash/intro
• Save state support
• Windows and Linux support - macOS may work, but not actively maintained
• Currently only .bin/.cue disc image formats are supported. Additional formats are planned
• Direct booting of homebrew executables

System Requirements

• A CPU faster than a potato.
• For the hardware renderers, a GPU capable of OpenGL 3.0/OpenGL ES 3.0/Direct3D 11 Feature Level 10.0 and above. So, basically anything made in the last 10 years or so.
• SDL-compatible game controller (e.g. XB360/XBOne)

Building

Clone the respository with submodules (git clone --recursive or git clone and git submodule update --init).

Windows

Requirements:

• Visual Studio 2019

1. Open the Visual Studio solution duckstation.sln in the root, or "Open Folder" for cmake build.
2. Build, binaries are located in bin/x64.
3. Copy the DLL files from dep/msvc/bin64 to the binary directory.
4. Run duckstation-x64-Release.exe or whichever config you used.

Linux

Requirements:

• CMake
• SDL2

1. Create a build directory, either in-tree or elsewhere.
2. Run cmake to configure the build system. Assuming a build subdirectory of build-release, cd build-release && cmake -DCMAKE_BUILD_TYPE=Release -GNinja ...
3. Compile the source code. For the example above, run ninja.
4. Run the binary, located in the build directory under src/duckstation/duckstation.

Android

Requirements:

• Android Studio with the NDK and CMake installed

1. Open the project in the android directory.
2. Select Build -> Build Bundle(s) / APKs(s) -> Build APK(s).
3. Install APK on device, or use Run menu for attached device.

• Tab: Temporarily disable speed limiter
• Pause/Break: Pause/resume emulation
• Space: Frame step
• End: Toggle software renderer
• Page Up/Down: Increase/decrease resolution scale in hardware renderers

Tests
