I made a spreadsheet of what Genesis/Megadrive games have been available on each Genesis mini, and threw in comparisons with Sega Genesis Classics software, and Nintendo Switch Online Genesis Expansion pack for the hell of it. The AtGames Flashback list is deceptive as around 28 of the games listed are "unofficial games" that AtGames is notorious for using as "filler titles" in its Flashback systems.
