I worked with the RetroDeck and underlying EmulationStation devs on a bug and they were incredibly cool and welcoming. I didn’t really have time to start taking on other tickets, but their documentation and availability made it easy to find the problem, get a workaround, and submit a fix.

Any mods that reduce the inventory managment aspect. I don’t care if it is cheating, but it really gets in the way of the gameplay and story for me. (At least on 1.something early I’ve just started a new playthrough.)
