The Asus ROG Ally is a fantastic handheld gaming console that's powerful enough to handle many AAA titles with ease. While it does have its flaws, many of us here at XDA use it for gaming and really enjoy the experience. It's a solid handheld gaming console that will let you enjoy all your favorite PC games even when you're away from your computer. But what if you want to play your PlayStation 5 games on the ROG Ally when you're lying in bed, for example, or the TV is being used by someone else?
Fortunately, you can enable Remote Play on your PlayStation 5 and use either the official PlayStation Remote Play client or a third-party alternative to play your favorite PS5 games on your ROG Ally or the new ROG Ally X.

Requirements for using your ROG Ally for PS5 Remote Play
First, enable Remote Play on the PS5
Regardless of which Remote Play client you choose, you will first need to enable Remote Play on your PlayStation 5 console. To do so, follow these steps:
1. Go to Settings Page on your PS5 console.
2. Select systemand then select Remote playback.
3. Switch Enable Remote Play Attitude.

Using the official Remote Play app on ROG Ally
Setting up the official Remote Play app
1. Go to PlayStation Remote Play website on your Asus ROG Ally.
2. Check the box to agree to the terms and conditions and select the Download Button.
3. Run the downloaded .exe file and follow the on-screen instructions to install it.
4. Once you are in the Remote Play app, click on the Sign in to PSN Button.
5. Enter your PSN credentials.
6. Select Confirm and continue to agree to the terms and conditions.
7. Select PS5and then connect your DualSense controller via a USB-C cable to use your PS5 remotely.
And that's how easy it is to set up and use the official PlayStation Remote Play app on your Asus ROG Ally. However, this method forces you to use the PlayStation 5's DualSense controller, which means you can't use the ROG Ally's native gamepad to play. That's not necessarily a deal-breaker, but something to keep in mind.
Using Chiaki on ROG Ally for PS5 Remote Play
A solid third-party remote play client
If you want to use your ROG Ally's native gamepad controls for PS5 Remote Play, you have no choice but to use a third-party client like Chiaki to play your PS5 games remotely on the ROG Ally. Chiaki is an unofficial, free and open-source client for the PS5 that works very well and hassle-free. With the steps highlighted below, you can set it up on your Asus ROG Ally in just a few minutes:
1. Go to this website on your ROG Ally to download Chiaki v2.2.0 (latest version at the time of writing) to download it.
2. Select the 'Chiaki-v2.2.0-Windows-x86_64.zip' to download the Windows client for your ROG Ally.
3. Extract the content from the downloaded file and then run chiaki.exe to begin.
4. Select the '+' icon in the upper right corner of the screen.
5. Enter your static PS5 IP as host. (You can find your IP address at “Settings -> System -> System Information” on your PS5).
6. You must now PSN Account ID (base64) and the PEN to complete your setup.
7. To generate the PSN Account ID:
- Go to https://psn.flipscreen.games/ in your browser and enter your PSN username.
- Copy the Encrypted ID (for Chiaki) and paste it into the field next to PSN Account ID (base64).
8. To generate the PEN:
- Go to Settings Page on your PS5.
- Choose systemfollowed by Remote playback.
- Choose Link device to generate the required PIN.
- Enter the 8-digit PIN in the text field next to PIN in the Chiaki app.
9. Click Register.
10. You will now see your PS5 on the main Chiaki screen, just double click on it to use it.
Chiaki works just like the official Remote Play app, except it doesn't force you to use the DualSense controller like the official one. This means you can use the native gamepad controls on your ROG Ally while playing your PS5 games remotely, making it in some ways an alternative to the PlayStation Portal handheld that Sony recently launched.
Play your favorite PS5 games remotely on ROG Ally
These are two easy ways you can play all your favorite PS5 games on the ROG Ally when you're not near your TV or someone else is using it. I personally prefer using a third-party client like Chiaki to enjoy Remote Play as it doesn't force me to use the DualSense controller. Using the official Remote Play app might be a good option if you're on a PC, laptop, or smartphone, but it's not ideal for use on handheld game consoles with their own controllers. In any case, you should be able to set up Remote Play and play your favorite PS5 games on the ROG Ally pretty easily, so give it a try.
