Chiaki is a Free and Open Source Software Client for PlayStation 4 and PlayStation 5 Remote Play for Linux, FreeBSD, OpenBSD, NetBSD, Android, macOS, Windows and Nintendo Switch.

Note that on latest PS versions you need to use your PSN account ID (PS4 7.0 or greater and PS5).

Installation

Download the .nro file and copy it into the switch/ directory on your SD card.

Recommended setup for best performance:

• Use 90DNS to allow Nintendo Switch lan.
• 802.11ac (a solid network connection for your Switch).
• Use a wired connection for the PS4 or PS5.
• Change the Nintendo Switch's network setting MTU from 1400 to 1500.

User guide

If your Console is on your local network, is turned on or in standby mode and does not have Discovery explicitly disabled, Chiaki should find it. Otherwise, you can add it manually. To do so, click the "+" icon in the top right, and enter your Console's IP address.

You will then need to register your Console with Chiaki. You will need two more pieces of information to do this.

Obtaining your PSN AccountID

Starting with PS4 7.0, it is necessary to use a so-called "AccountID" as opposed to the "Online-ID" for registration (streaming itself did not change). This ID seems to be a unique identifier for a PSN Account and it can be obtained from the PSN after logging in using OAuth.

A Python 3 script which does this is provided in scripts/psn-account-id.py. Simply run it in a terminal and follow the instructions. Once you know your ID, write it down. You will likely never have to do this process again.

Obtaining a Registration PIN

To register a Console with a PIN, it must be put into registration mode.

• To do this on a PS4, simply go to: Settings > Remote Play > Add Device.
• Or on a PS5: Settings > System > Remote Play > Link Device.

You can now double-click your Console in Chiaki's main window to start Remote Play.
