Thanks. Yeah I use it for other things like DS4 on Switch. But I've been trying for what I said. I tried the route of trying to have the joy-cons emulate xbox controllers so I could then make the xbox controller appear as a ds4 to the remote play app but no luck.
Something funny though is that...
I was wondering if it was possible to use the MAGIC-NS to connect Joy-Cons to the PC and use them to play PS4 Remote Play. I've tried a million things but can't get them working. I can connect the Joy-Cons to the PC but I can't play anything, let alone the Remote Play app.
