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.

DuckStation supports cue, iso, img, ecm, mds, chd, and unencrypted PBP game images. If your games are in other formats, you will need to re-dump them. For single track games in bin format, you can use https://www.duckstation.org/cue-maker/ to generate cue files.

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!)
- PGXP for geometry precision, texture correction, and depth buffer emulation (fixes texture "wobble"/polygon fighting)
- Adaptive downsampling filter
- Post processing shader chains (GLSL and experimental Reshade FX).
- 60fps in PAL games where supported
- Per-game settings (set enhancements and controller mapping for each game individually)
- Up to 8 controllers in supported game with multitap
- Controller and keyboard binding (+vibration for controllers)
- RetroAchievements in supported games (https://retroachievements.org)
- Memory card editor (move saves, import gme/mcr/mc/mcd)
- Built in patch code database
- Save states with preview screenshots
- Blazing fast turbo speeds in mid to high end devices
- Emulated CPU overclocking to improve FPS in games
- Runahead and rewind (do not use on slow devices)
- Controller layout editing and scaling (in pause menu)

DuckStation supports both 32-bit/64-bit ARM, and 64-bit x86 devices. However, due to it being a more accurate emulator, hardware requirements can be moderate. If you have a 32-bit ARM device, please do not expect the emulator to perform well - you will need at least a 1.5GHz CPU for good performance.

If you have an external controller, you will need to map the buttons and sticks in settings.
