It’s probably possible and safe for roms, but then there are already more or less complete packs for basically every console and retro computer ever made so it’s not that useful.

Even then I wouldn’t do it. Installing games takes a while too, so it’s not much of a time-saver compared to automatically organizing movies/shows.

And the risk of getting a misleadingly named game with malware is too high. Remembering to sandbox isn’t easy either, after possessing them for a while. Untrusted files should never be on a computer, imo. But I don’t pirate games, so take my advice for what it is.
