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?

In Part 19 of Glitched Worlds, we explore Worlds 241-250, some of the strangest levels hidden inside Super Mario Bros. Along the way Mario revisits Coin Heaven, falls into mysterious voids, faces Bowser yet again, and discovers worlds that seem completely unfinished. As we get closer to World 256, the glitches become even more unpredictable. Some worlds loop endlessly, some send Mario through familiar levels, and others barely function at all. What happens when the hidden worlds begin to break down completely?
