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.

DuckStation features a fully-featured frontend built using Qt, as well as a fullscreen/TV UI based on Dear ImGui. Other features include:

• Hardware renderer supporting OpenGL and Vulkan APIs.
• Upscaling, texture filtering, and true colour (24-bit) in hardware renderers.
• PGXP for geometry precision, texture correction, and depth buffer emulation.
• Accurate blending via Rasterizer Order Views/Fragment Shader Interlock.
• Texture replacement system in hardware renderers.
• Vectorized and multi-threaded software renderer.
• Motion adaptive deinterlacing.
• Adaptive downsampling filter.
• Screen rotation for vertical or "TATE" shmup games.
• Post processing shader chains (GLSL and Reshade FX).
• Border overlays/bezels displayed around game content.
• "Fast boot" for skipping BIOS splash/intro.
• Save state support, with runahead and rewind.
• Supports reading directly from CD, bin/cue images, raw bin/img files, MAME CHD, single-track ECM, MDS/MDF, and unencrypted PBP formats.
• Preloading of disc images to RAM to avoid disk sleeping hitches.
• Merging of multi-disc games in game list/grid with memory cards shared between discs.
• Automatic loading/applying of PPF patches.
• Direct booting of homebrew executables.
• Direct loading of Portable Sound Format (psf) files.
• Time stretched audio when running outside of 100% speed.
• Digital and analog controllers for input (rumble is forwarded to host).
• GunCon and Justifier lightgun support (simulated with mouse).
• NeGcon support.
• Controller presets and per-game configuration.
• Automatic content scanning - game titles/hashes are provided by redump.org.
• Optional automatic switching of memory cards for each game.
• Supports loading cheats from existing lists.
• Memory card editor and save importer.
• Emulated CPU overclocking.
• Integrated and remote debugging.
