Every game on one shelf on Apple TV

Posters, not filenames. Continue Playing sits on top, like the shows you're partway through.

The Playbox library on Apple TV, with a Continue Playing row and a shelf of NES games

The problem

Your games are a folder of filenames on a drive somewhere. To play one you open a file browser on a television, scroll a list of .nes files, and hope you remember which of them is the one you wanted.

What Playbox does

It reads the folder and builds a shelf. Each game gets a poster: the picture you put next to it, or the screen you were last looking at, or a typeset tile with its name. The row across the top is the games you were in the middle of, newest first.

That is the whole library. There are no folders to expand, no metadata to fill in, and nothing to import. The folder on your NAS is the library, and adding a file to it adds a game.
