Do we have a fix or workaround yet for adding Earthbound Beginnings?

How can the Super Mario Bros. 2 and 3 database bug still be happening after all this time? :(

Similar problem with Diablo II: Lord of Destruction and beyond.
If you are looking for it, you will not find it even if it is present in IGDB.
This thing that you can't add games manually is annoying.
If they don't fix the search and add the ability to add games manually they force me to switch to Playnite.
Although prefer to use GOG Galaxy.

Yes I know, but I would like to catalog all games including physical ones .. not necessarily run it.
The function of adding a game manually would be enough.

You can add another "Diablo 2" (the same you already have), from "Add Games & Friends -> Add game manually", search "Diablo 2" and then click "Mark as Owned"

Now you'll have a "Diablo 2" with two grouped entries (you can switch them right clicking on the thumbnail or clicking on the diamond icon at the top of the game page).

The new one can be linked to the LOD executable.

Unluckily, you can't customize it (like changing images or title), because the appearance of the entry is shared between the two games...

An alternative could be to "Mark as Owned" a random game that you will never get, and them customize its entry entirely, calling it "Diablo II - LOD", changing images and linking it to the LOD executable.
This way you will have two visible separate entries.
