I wanted to jump back on this thread to say I got this up and running on a Raspberry Pi 5 which is also hosting my RetroNAS setup. I'm now building my database.
It is a very polished project! Thank you very much.
Just wanted to say that this project is amazing! I stumbled upon this while I was looking for a better way to track my collection. Thank you for your time and effort on this. It really fits so well for vintage collectors.
