@hook Online + Expansion Pack has the first two Genesis 𝘎𝘰𝘭𝘥𝘦𝘯 𝘈𝘹𝘦 games. Failing that, and assuming the Capcom Beat-'Em-Up Bundle's options aren't to your liking, the closest thing out there is likely ACA Neogeo 𝘚𝘦𝘯𝘨𝘰𝘬𝘶 2, unless 𝘚𝘩𝘪𝘯𝘨𝘦𝘯 𝘚𝘢𝘮𝘶𝘳𝘢𝘪-𝘍𝘪𝘨𝘩𝘵𝘦𝘳 is something you can tolerate (I can, but it's an acquired taste). If you don't mind top-down action rather than side-view brawling, 𝘝𝘢𝘯𝘥𝘺𝘬𝘦 will scratch the thematic itch like nothing else.
