@Import emulators/duckstation-qt

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.

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.
