DuckStation is a free and open-source PlayStation emulator developed primarily by stenzek. It features PGXP, upscaling, texture filtering, overclocking, advanced "cheat" code support, CHD support, and a graphical interface.

DuckStation is focused on playability, speed, and long-term maintainability. The goal of the emulator is to be as accurate as possible while maintaining performance on a broad range of devices. "Hack" options are discouraged, and the default configuration should support all playable games with only some of the enhancements having compatibility issues. 64-bit CPUs are required for recompiler support for maximum performance.

DuckStation was used as a testing ground for code that would be added to Dolphin.[1] stenzek has even said the UI was pulled directly from Dolphin, since it was "designed in conjunction with actual UI/UX people".[2]

The Qt frontend includes an automatic update checker. Builds downloaded after 2020/08/07 will automatically check for updates each time the emulator starts, this can be disabled in Settings. Alternatively, you can force an update check by clicking Help->Check for Updates.

  2. stenzek on Reddit. "Yep it is heavily influenced by Dolphin. I'm terrible at UI/UX design so I borrowed Dolphin's, since it's been designed in conjunction with actual UI/UX people."
