DuckStation is an simulator/emulator of the Sony PlayStation(TM) console, focusing on playability, speed, and long-term maintainability. The goal is to be as accurate as possible while maintaining performance suitable for low-end devices. "Hack" options are discouraged, the default configuration should support all playable games with only some of the enhancements having compatibility issues.
A "BIOS" ROM image is required to to start the emulator and to play games. You can use an image from any hardware version or region, although mismatching game regions and BIOS regions may have compatibility issues. A ROM image is not provided with the emulator for legal reasons, you should dump this from your own console using Caetla or other means.

Requirements (Debian/Ubuntu package names):
- CMake (
- SDL2 (
- pkgconfig (
- Qt 5 (
- libevdev (
- git (
git) (Note: needed to clone the repository and at build time)
- When Wayland is enabled (default):
- Optional for RetroAchievements (on by default): libcurl (
- Optional for framebuffer output: DRM/GBM (
- Optional for faster building: Ninja (
- Clone the repository. Submodules aren't necessary, there is only one and it is only used for Windows (
git clone https://github.com/stenzek/duckstation.git -b dev).
- Create a build directory, either in-tree or elsewhere.
- Run CMake to configure the build system. Assuming a build subdirectory of
cmake -Bbuild-release -DCMAKE_BUILD_TYPE=Release. If you have installed Ninja, add
-GNinjaat the end of the CMake command line for faster builds.
- Compile the source code. For the example above, run
cmake --build build-release --parallel.
- Run the binary, located in the build directory under
