Akira is a wrapper around chiaki-ng to provide a GUI for using the chiaki-ng library to access the Playstation Remote Play protocol on the switch, enabling it to work as a Playstation client.

It uses a fork with some switch specific changes which I hope to upstream eventually, mainly around the cryptography section for PSN handshakes/connections. This fork is located here.

I previously did this in tree, however due to the amount of changes that I was making to this it was much better to take it out of tree than to break the .nro build for everyone. I should also point out that I don't own a ps4, so I don't know if it will work for it. Let me know!

Other custom libraries include a forked cURL with websockets enabled and the libNX VTLS work done by yellows8 to utilise libNX for cryptography purposes where possible.

As with Chiaki

  • Make sure you have a good wifi network. having a 5G wireless network is insufficient, you need to have a good signal to it.
  • The access point preferably be wired backhaul.
  • Your router shouldnt be dropping packets due to load.
  • Make sure that your ps4/5 is connected by ethernet. It is possible to stream via wifi, I have done it, but you need all of the above too.
  • Make sure you dont have any rouge sysmodules that is consuming 100% of your core 3. This is very important.
  • PLEASE MAKE SURE YOUR NETWORK IS STABLE AND NOT DROPPING ANY PACKETS/UNDER HEAVY LOAD

Here's an example of a bad network config that did not have VLAN filtering enabled, and was killing the access points by spiking them to 100% CPU usage by flooding them with bad packets. As you can imagine, the game was almost unplayable.

In my tests using a clean emummc, I found out that rouge sysmodules may cause core 3 to go to 100%, you can see this by using the tesla system status overlay homebrew

Please only use a clean emunand from https://switch.hacks.guide/

Please read the wiki to the right.

Good luck!
