For those who don't know, chiaki4deck is an open-source software to "Remote Play" PS5 games on Steam Deck (and linux / mac), which aren't officially supported by Sony.
Main things (in my opinion):
New touch-friendly and controller navigable GUI
Adds option to sleep PlayStation when sleeping Steam Deck
Resume connection from sleep mode on Steam Deck
Ability to login to PlayStation for account ID via GUI
I love the idea of chiaki so I can play my PS4 games while my wife watch TV, I just wish I could do something about the latency that isn't "plug everything in to Ethernet". I'd love to use it more, but I can't find anything that has worked
