About this game

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 or other means. These are usually dumped as "scphNNNN.bin" or "ps-NNN.bin", where NNNN is the model number or ROM version, and should be 512KB in size. 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 convert or 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 (recommended) 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
- 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
- Rewinding (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.

**For high upscaling (more than 2x) you will need at least a mid range device. This is because of how many pixels the emulator needs to render/shade - it is not a question of optimization.**

Instructions:

1. Install and run the app for the first time.
2. Add game directories by tapping the add button and selecting a directory. You can add additional directories afterwards by selecting "Edit Game Directories" from the menu.
3. Tap a game to start. When you start a game for the first time it will prompt you to import a BIOS image.

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

This is an amazing emulator, one of, if not, THE best you could get. Once you get one of those BIOS for it, you're in for a fun time. Limitless customization, snappy controls and no ads. And this is free! Wish I could give it 11 out of 5 stars, would recommend. EDIT: OK something weird happened when playing Abes Oddysee. At the end of the game, you have to pull a lever to get to Molluck. But the lever doesn't work. It works with other emulators. Still a good emulator tho, and still 5 stars.

Phenomenal emulator. Absolutely everything you could ever want and a whole lot more. Upscaling looks amazing on a 1440p display, easy controller pairing, no ads or annoyances. Just quality emulation thanks to the hard work of dedicated hobbyists. If there was a way I could support the efforts of the developers I gladly would. Thanks for all the hard work.

An excellent emulator, easy to run, user friendly, honestly the only thing that could come to mind to improve it is give it a way to set a cloud service like google drive or dropbox as a game save sync/backup service, so that players can easily sync data to or from the cloud storage to the device. Maybe have it check for game files that have been updated since the last sync and then have it select those when doing an auto sync and then a manual sync for doing specific saves only
