Package: nestopia Version: 1.47-2 gnome-games-app is now in Debian unstable. (It will not be in stretch.) It can use libretro cores like nestopia if there is a .libretro file describing it.
gnome-software can show nestopia as an Addon for gnome-games-app if nestopia includes appstream metadata for that. I am attaching a patch in the next email that I successfully applied on Ubuntu 17.04.
