Sergio, I opened a merge request for this issue, because I know when we discussed this in 2017, you didn't think it was appropriate to add these .libretro files to each package.
Since then, we're already adding AppStream metadata to these packages so I don't see the harm of adding one more small file to our packaging and I'd like to do that work and the uploads. I think adding that to each package is the best place for that metadata. With the exception of libretro-core-info, metadata for a package belongs in that package not somewhere else. Please take a look at this soon since I'd like to fix this issue in time for Buster's release. https://salsa.debian.org/games-team/mgba/merge_requests/1 https://gitlab.gnome.org/GNOME/gnome-games/issues/79 Thanks, Jeremy Bicha
