Sorry, haven't logged on in a bit. I use OPNSense on an old PC for my firewall with the wireguard packet installed.
Then use the wireguard client on my familys phones/laptops that is set to auto connect when NOT on my home wifi. That way media payback, adguard-home dns and everything acts as seamless as possible even when away while still keeping all ports blocked.
If you still have your game disk to rip you can use this to play it on pc.
I have an old pc with an i7-6700 cpu and older graphics card using a ps5 controller I bought from a pawn shop. Been playing OG God of war and Shadow of the Colossus on it. Plays just as good if not better than real ps2 hardware.
I would let you custom map keyboard keys to controller keys too
