Step beyond Worlds 1–8 and into the unknown. In this series, Retro Mark explores the hidden and glitched worlds of Super Mario Bros. levels that were never meant to be seen. Using techniques like cartridge swapping, Game Genie codes, and hex editing, each episode dives deeper into broken, unstable, and sometimes completely unplayable versions of the game. From looping levels and corrupted environments to worlds that simply stop working… this is the most immersive journey into Mario’s glitched reality. How far do the Glitched Worlds go?

We return to the forgotten depths of Super Mario Bros. to explore Worlds 19 through 28 of the infamous 256 Glitched Worlds: corrupted stages, impossible layouts, soft-locks, cycling levels, and a Bowser fight that breaks the entire game. From endless cloud highways to underwater castles made of bricks, to levels that loop forever or instantly kill Mario… this is the weirdest Mario content ever created, and Nintendo never meant anyone to see it. This is Part 2 of my full breakdown of all 256 glitched worlds in Super Mario Bros. PART 3 (Worlds 29–38) coming soon! Subscribe so you don’t miss it!
