Okay, so this is one of those weird unofficial Mario ports—someone basically crammed the original Super Mario Bros. into a Sega Genesis cartridge. It’s not perfect (the colors are a little off, and the jumping feels slightly heavier), but there’s something hilarious about playing Mario on a Sega console. You still get the classic levels, Goombas, and that iconic underground theme, just with a slightly different vibe.

If you grew up with the NES version, you’ll notice the differences right away. But if you’re just curious about gaming oddities, it’s a fun little piece of "what if" history. Just don’t expect Nintendo-level polish.
