Super Mario 3 Expert is basically the original Super Mario Bros. 3, but cranked up to eleven. Someone took the SNES classic and made it brutal—extra enemies, trickier jumps, and levels that’ll test your patience. At first, it feels familiar, but then you hit the first world and realize you’re in for a rough ride. Those hammer bros? Now they’re everywhere. That easy level you breezed through as a kid? Good luck.

It’s not unfair, though—just demanding. You’ll need to actually learn the layouts, time your moves, and maybe even grind for power-ups. If you’ve played the original to death and want something that makes you sweat, this romhack delivers. Just don’t throw your controller.
