When you buy a Steam Deck, the beauty isn’t just its portability; it’s also that you don’t have to be locked into playing directly on the ecosystem if you’re a multi-platform gamer. That’s because the Steam Deck has nifty unofficial apps you can download through Discover Software Center in Desktop Mode that stretch its capabilities. These apps let you access games you’ve bought from other launchers, and some you couldn’t get natively, like your PlayStation 5 library and your phone.
However, for your Steam Deck to play PS5 games, you must own a working console. Plus, you need to download the Chiaki4deck app (also called Chiaki-NG) and enable Remote Play on your console, since you won’t use the Steam Deck to access your library directly. Instead, you’ll stream, so you need a stable connection for smooth performance.
Lastly, Steam Deck controls translate fairly well to a PS5 DualSense controller automatically (you can also configure this during the Chiaki4deck setup); the trackpads on the Steam Deck mimic the PS5 DualSense’s touchpad and PlayStation button. For extra customization, consider remapping it yourself or downloading a community template.
How to set up Chiaki4deck to stream your PlayStation 5 games
To stream your PlayStation 5 games from the Chiaki4deck app, both your Steam Deck and console must be on the same network. You can do this remotely by port forwarding (the old way) or using the “Remote Connection via PSN” option if your app is v1.7.0 or later. During initial setup, keep them on the same network to ensure they link properly (you only need to do this once).
First, open Desktop Mode on your Steam Deck by holding down the power button. Once you’re in Desktop Mode, open the Discover Software Center and search for “Chiaki4deck or Chiaki-NG.” Select it to download and install it. After installing the app, you can optionally create a non-Steam game and remap the controls — this step is recommended.
The next step is to register your PS5 console in the Chiaki4deck app. The app should prompt you to do so during initial setup. Just note that you’ll also need to do this on your console, since it requires entering a PIN to link your devices through the PlayStation Remote Play menu (navigate to “Settings” > “System” > Remote Play”). Once you start Chiaki4deck, you should see a window with a Register button that prompts you to enter the PIN, your PSN account ID, and Host. The latter should auto-populate if you’re on the same network and logged into your PSN account; otherwise, you may need to use a public lookup tool. After registering, open the Chiaki4deck app in Game Mode, select “Play,” to connect to your PS5 while it’s on or in Rest Mode (it must be configured to stay connected to the internet in Rest Mode settings).
What to do if you don’t have a PlayStation 5
As great as it is to turn your Steam Deck into another device for streaming your PlayStation 5 games, it isn’t very helpful if you don’t own the console or yours isn’t working. Also, the experience depends on your connection; a poor network means more latency while streaming. As such, you have only a few options. One, you can just buy some of Sony’s ported titles directly. Great options include “God of War: Ragnarök,” “Ghost of Tsushima: Director’s Cut,” and “Horizon Zero Dawn,” which perform well on the Steam Deck. You can view a full list of Sony titles through PlayStation Studios’ Steam page.
The second option is “technically” emulation (emphasis on the quotations). However, this one isn’t recommended since the emulator is still in its early stages, meaning it’s a work in progress and remains experimental. If the project interests you, you can check out SharpEmu, which supports Windows, Linux, and macOS. Currently, the emulator supports only a few titles, and much less so on the Steam Deck.
The first “working” emulated title for the Steam Deck is “Astro Bot,” but it’s more of a proof of concept, showing only the title and loading screen at 0.5 to 1 FPS. The other major downside is that most titles won’t be viable, as the hardware doesn’t come close to a PS5 without rigorous tuning. If anything, this might become more of a job for the Steam Deck 2 when Valve announces and releases it.
