I never has an original psp, but I had a psp-go. It was great! I primarily used it to emulate the nes and Genesis. Not many people liked the other slide out screen aesthetic but it was one of my favorite parts of the design. It reminded me of the Motorola sidekick.

Airvpn can generate a pure wireguard (or openvpn) config. No vendor specific GUI needed. I have several boxes using it and have had zero issues. Plus their support is awesome.
