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?

Deep inside Super Mario Bros. exists a hidden level so unstable that Mario can’t survive more than a second. Known as World 14, this glitched world drops the player into infinite darkness, broken geometry, looping castle hallways, and total game failure. In this episode of Glitched Worlds Investigations, we explore what happens when the game loads a level that was never finished or never meant to be seen. Using Game Genie codes and emulator tools, we push deeper into World 14 and uncover looping structures, corrupted assets, disappearing HUD elements, and crashes that don’t behave the same way twice. This isn’t just a glitch. It’s a world that actively resists exploration. ~ What causes World 14? ~Why does the level collapse differently every time? ~And why does the game freeze when pushed too far?
