I wrestle with this for sure. Not all games need to be shiny and restored. But I do enjoy that process. I would focus on getting it to play perfectly. Dial it in. Get everything to work the way it did when it left the factory.
I have an EBD and a new PF but it will be a while before I need to swap it. My game has mechanical issues that Iām sorting out and as a matter of hard lessons learned, you should swap a game that works...
