@BuZz Thanks, I didnt realize that.
I discovered TriPi so for the next pi build I will be using that rather than doing all individually like I did with my current RetroPie box.
The VPN into home network to access steam games remotely works as a user in this thread got it working: https://github.com/RetroPie/RetroPie-Setup/issues/1082 Unfortunately I cant seem to send him a message on GitHub.
