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. It received a significant amount of popularity, even surpassing ePSXe and PCSX-Reloaded, due to its use of own proprietary plugins, incredible emulation accuracy, comfortable and appealing Qt-based interface, good variety of emulation settings, and good level of compatibility.

DuckStation is designed for playability and speed, with the goal of being as accurate as possible while maintaining performance on a broad range of devices. The default configuration is intended to support all playable games, with only some of the enhancements having compatibility issues. 64-bit CPUs are required for maximum performance using the recompiler.

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."
