Chiaki
~5 min read
Chiaki is an open-source implementation of Sony's Remote Play protocol. The Switch port (chiaki-nx) lets you play your home PS5 / PS4 games on a Switch. Mnemonic: Moonlight = PC, Chiaki = PlayStation.
What you need
- A PS5 or PS4 (signed into PSN)
- Your PSN Account ID (registration code) — extracted with a helper tool
- Same LAN or stable WAN
Getting the registration code
- On PC, install chiaki-ng (an active fork of Chiaki).
- Use "PSN ID" tool to fetch your base64 Account ID from your online ID.
- Enter that into Switch-side Chiaki settings.
Switch-side setup
- Drop the chiaki-nx NRO into
/switch/chiaki/.
- Launch from hbmenu.
- Enter the Account ID + 8-digit PIN (PS5 Settings → Remote Play → Register Device shows it).
- Once paired, you can wake the PS5 from rest and play.
Latency: 30–60 ms on 5 GHz LAN. 80–150 ms over WAN. FPS-shooters tough; RPGs / action are fine.
PSN ban risk: Chiaki is unofficial. Sony could in theory ban accounts using it — actual cases are rare, but it's not zero risk.
vs Moonlight-NX
Moonlight-NX is for PC (NVIDIA GameStream / Sunshine); Chiaki is PlayStation-only. The protocols are fundamentally different — they can't substitute for each other. Run both and your Switch becomes a remote-play universal client.
Relation to the secretchat.tel loader
Chiaki and our loader both run as homebrew NROs under Atmosphère, sharing the same SD. Different use cases (Chiaki = PS5 Remote Play, loader = Apex), so no overlap.
