Pkg only but they're fake pkg not retail.
Most games have been backported to 5.05 so there's a lot available, and they're very easy to find (on reddit etc).
PS4 HEN isn't persistent, if you power off completely you need to exploit again. Use rest mode and it's still there.
Install pkg via debug settings...
But even power off isn't so bad on 5.05 because it has high exploit success (like 98%) and you can cache everything you need for offline.
It isn't as stressful as I thought it would beBut I guess I've been reading too many complaints about higher firmware issues.
