DuckStation is a Sony PlayStation ™ / PSX / PS1 console simulator / emulator focused on playability, speed and long-term maintainability. The goal is to be as accurate as possible while maintaining high productivity.
The “BIOS” ROM image is required to run the emulator and games. The ROM image is not provided with the emulator for legal reasons, you must reset it from your console using Caetla or other means. They are usually downloaded as “scphNNNN.bin” or “ps-NNN.bin”, where NNNN is the model number or ROM version, and should be 512KB in size. Games do NOT come with an emulator, it can only be used to play legally purchased and discarded games.
DuckStation supports cue, iso, img, ecm, mds, chd games, and plaintext PBP game images. If your games are in other formats, you will need to convert or re-dump them. For single track bin games, you can use www.duckstation.org/cue-maker/ to create cue files.
Possibilities:
– OpenGL, Vulkan (recommended) and software rendering
– Upscaling, texture filtering and true color (24 bit) in hardware renderers
– Widescreen rendering in supported games (no stretching!)
– PGXP for geometry precision, texture correction, and depth buffer emulation (fixes texture jitter / polygon fighting)
– Adaptive downsampling filter
– 60fps in PAL games where supported
– Settings for each game (customization of improvements and mapping of controllers for each game individually)
– Up to 8 controllers per supported game with Multitap function – Snap
controller and keyboard (+ vibration for controllers)
– RetroAchievements in Supported Games (https://retroachievements.org)
– Memory card editor (move save, import gme / mcr / mc / mcd)
– Built-in patch code database
– Save states with preview screenshots
– Super fast turbo speeds on mid to high end devices
– Emulated CPU overclocking to improve FPS in games
– Rewind (do not use on slow devices)
– Editing and scaling controller layout (in the pause menu)
DuckStation supports both 32-bit / 64-bit ARM devices and 64-bit x86 devices. However, due to the fact that this is a more accurate emulator, the hardware requirements can be moderate. If you have a 32-bit ARM device, don’t expect the emulator to perform well – you’ll need a processor with a clock speed of at least 1.5GHz for good performance.
