More About DuckStation

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.

This emulator is perfect! I literally have spent the whole night trying to fix a game on other emulators, epsxe had an audio issue and fpse had some resolution issues, and then i found this emulator, and all it took me was 10 minutes and everything is fixed and it works perfectly. Thank you so much for this app and thanks for making it free! Goodluck on your next projects man!

This emulator runs everything I've tried on it extremely well on my Galaxy S8. So, I thought this would be perfect for the Nvidia Shield Tv, the only problem is that the Play store on the Shield doesn't have this app. I even tried to sideload it onto the Shield but it wouldn't install. 5 stars if they ever get it onto the Android TV version of the Play store.

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.

Was great until the update. Now the games that were working are having issues and struggling. The fastforward button at full 1000 percent speed isn't as fast as the original. I had to re import all my save files and more.. it was perfect the way it was. Simple and functioned amazing. Now it's got more features but runs worse.. sometimes when something isn't broken don't try to fix it.. one star until they resolve the issues.

Like many others, I have trouble knowing where I'm supposed to put my files once I've downloaded them. There's no clear answer on if I should make a game folder or what. And regardless of whether they load up or not in the app, I never get game covers. Just blank pictures inside the app making everything seem so jumbled up and hard to find. Otherwise it works great and I love all the options. PGXP is a godsend and seems to work better here than it does in all the other emulators.

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

I love this emulator. Simple UI and easy to navigate, no ads from what I've been seeing, and emulation runs great. I had an issue before where things were too quick and registered twice, but I realized that was my bad and I overclocked the emulation to 200%. If you're using bin and cue files, open the cue files. I'm pretty sure isos will just open normally. Love your work, maybe if you have detected a rom the first time itll stay on the main page, but I just press play anyway.

(Edit: there is a few things I'd like to suggest though. First is anisotropic filtering. Second is FXAA as a post-processing option. And third is a screen filtering option separate from post-processing or texture filtering. Keep the good work devs!) What can I say other than "Options galore!" It's extremely well optimized very intuitive and has more options and settings to tweak than I've seen in any other PS1 emulator. This is easily the best PS1 emulator I've ever used!

Great Emulator! If you're reading this and having frame rate issues. Go to settings, then system tab scroll down to the very bottom. DISABLE RUN-AHEAD. It seems to be on 1 frame by default. Which is just enough to make you think something is up with the app.. or device. MUCH LOVE TO THE DEV(S) & HAPPY HOLIDAYS!

Compared to other options for both mobile and desktop operating systems, ds has the least frustrating in-game ui to use, is maintained, and requires the least amount of wrestling with the configuration settings to even get in game. The setup wizard for this version of ds wants individual bios files and not a folder of files, idk why you cannot select a folder to scan at setup. I have been using the desktop version on my main desktop and my Steam Deck and it works >95% of time.

This emulator works well but I'm having a problem with analog control. My phone is an s21 fe and I've tested 3 controllers. The razer Kashi v1, the gamesir usbc, and a sn30pro and all of them have problems with diagonals on the analogs. I tried changing the axis scale so I turned it down to .85 and nothing changed. So I tried turning it up to 1.15 and still nothing. But after that it seems analog broke if I set the scale to 1.00 or less it doesn't work but a scale is 1.01 or greater does.

Definitely one of the better PSX emulators. It has handled every BIOS I've used on it with no problems. It has, also, run several patched ISOs without crashing, too. Edit: the update definitely did this app dirty. It's not totally unplayable, but it's not good any more, either. I get that you'd have been unlisted without switching to API31, but still...

EDIT: I figured out what I was doing wrong. You cannot just pick any folder on my phone for the gameslist to look from, I need to put all of the resources in the /duckstation folder the app made in order for the gameslist to be usable. So far, for the games I've tried, Duckstation works great on my device (Samsung Galaxy 9-era); however I cannot make the games list work. I've tried everything I could to the games list, but I have to manually load the files every time.

This emulator is perfect don't know why it doesn't have 5 outa 5. People aren't greatful for what they get, its that or rate it lower because they can figure something or it runs to slow on their devices which has nothing to do with the app itself sometimes the device is the problem and can't handle it. If you can't figure things out on your own be smart enough to at least YouTube how to set this emulator up.

Performancewise, this psx emulator is WELL above others available for android, such as epsxe and the pcsx core from retroarch. It also has a much easier UI, supports CHD format, and the upscaling options are VERY impressive. The most recent update adds button mapping support, but when using an 8bitdo controller in "Pro controller mode" (which seems to have the lowest amount of input delay for me) the D-pad doesn't work properly at all.

-From Pixel4a running Android 11- For an emulator, it runs both 2d and 3d games really well, if the rips are good. When adding enhancements like resolution scaling and antiailiasing, most games will look better. It is recommended to play with a controller hooked up for a better experience, but they do have a touch screen layout as a last resort. At the moment, they do have a rewind binding, but no setting for the rewind itself. The app is constantly updated, so it's very up to date.

Great! The latest update has lost my saves though. Following the instructions I get a message saying that no importable files were found. HUGE bummer there. I can see the files. The app can see the files. Not sure what is wrong or where to manually move the files too. Going to try to move them, delete the folder, create a new save, then move them to wherever the new folder is. I guess. Hopefully that works. Edit- It didn't work. Where are the New version files being saved?

I like it, BUT I hate that everytime I close it and reopen it again, it has to rescan my roms. And I have more than 100 PSX roms. A lot more lol. So in order to play roms asap on the go, I have to ALWAYS have this app running in the background. It takes 5 mins or more each time when it comes to rescanning. Especially when I turn my phone off. It has to rescan when using it again after turning my phone back on. Smh. Please fix! This is the only emulator that gives me this issue.

So, I've tried multiple PS1 emulators, with varying degrees of quality in games. Vagrant Story has always given me issues with graphics and audio. Until I tried Duckstation. Ran flawlessly with default settings. Running on a Samsung A53 5g, low to mid-range device as of last year. Not sure about some of the low ratings. Easy to set up, though it does take little software knowhow to do so. Lots of features, and - free.

Great PSX emulator, plays what I want no issues. I can't recommend it on Android 13 though.. All the system files like save data is hidden behind android/data folder for the app. So you won't have access to save files unless you directly connect it to a pc to get it. Third party apps like Zarchiver or FTP cannot access it either. The hassle to backup your saves is a concern. Devs should add option to have save files stored in a more accessible area, also option to edit cheat files. A+ otherwise.
