F-Mario SNES is one of those weird, janky Mario bootlegs that somehow feels both familiar and totally off. You've got the usual running and jumping, but the physics are just... wrong? Like Mario slides a little too much after stopping, and the enemies move in ways that don't quite make sense. The levels are clearly trying to mimic the real Super Mario World, but with awkward gaps and weird power-up placements.

Honestly, it's kind of fascinating in a "so bad it's good" way. The graphics are this bizarre mix of stolen assets and poorly redrawn sprites—some of the Goombas look like they've been stretched in MS Paint. If you're into weird ROM hacks or just want to see how badly someone can mess up a Mario clone, give it a shot. Just don't expect it to play anything like the real thing.
