DuckStation is an simulator/emulator of the Sony PlayStation(TM) / PSX / PS1 console, focusing on playability, speed, and long-term maintainability. The goal is to be as accurate as possible while maintaining high performance.
A "BIOS" ROM image is required to start the emulator and to play games. A ROM image is not provided with the emulator for legal reasons, you should dump this from your own console using Caetla/Unirom/etc. Games are NOT provided with the emulator, it can only be used to play legally purchased and dumped games.
Features include:
- OpenGL, Vulkan and software rendering
- Upscaling, texture filtering, and true colour (24-bit) in hardware renderers
- Widescreen rendering in supported games (no stretching!)
