Thank you, it turned out to be the SaltyNX sysmodule I had loaded, without that the nro starts fine now.
After entering the pin I now get green screen, besides the two added lines you mentioned, the .conf it also has "rp_key_type = 2". My ps4 is on 5.05 so I'm not using accountid.
edit: ok it's working, as long as I rewrite the original .conf file each time, and connect using a pin. Further connections without rewriting the .conf just give green screen, as other people have been finding. The video stream just about keeps it together at 30/360, any higher and it breaks up a lot. I found the home button mapped to minus, which is handy, unfortunately couldn't find a touchpad press for The Last Of Us in-game menu. Maybe that could be mapped to a screen touch - most games like TLOU just use the touchpad as a button, so you don't need to bother with touch coordinates etc.
