Akira

Akira wraps chiaki-ng in a GUI so you can use the PlayStation Remote Play protocol on the Nintendo Switch. It turns the Switch into a PlayStation client.

Start here: Registering and Connecting.

This used to live in-tree. There were too many changes to keep it there without breaking the .nro build for everyone, so it's out of tree now. I don't own a PS4, so I can't tell you if it works on one. Let me know.

Other custom libraries: a forked cURL with websockets enabled, and the libnx vTLS work by yellows8 so cryptography runs on libnx where possible.

Network requirements

Your network matters more than anything else here.

warning

• You need a good wifi network. A 5 GHz network on its own isn't enough. You need a strong signal to it.
• The access point should have a wired backhaul.
• Your router should not be dropping packets under load.
• Wire your PS4/PS5 with ethernet. Wifi streaming works, I've done it, but only if everything above is true.
• Kill any rogue sysmodules pinning core 3 at 100%. This matters.
• Your network must be stable and not dropping packets or under heavy load.

Here's a bad network config that didn't have VLAN filtering enabled and was killing the access points by flooding them with bad packets, spiking them to 100% CPU. The game was almost unplayable.

On a clean emuMMC, I've seen rogue sysmodules drive core 3 to 100%. The Tesla system-status overlay homebrew will show you.

tip

Use a clean emuNAND from switch.hacks.guide.

Good luck.
