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?

What happens when the Glitched Worlds stop progressing… and start repeating? In this episode of Glitched Worlds, I explore Worlds 79–88, where Super Mario Bros begins to behave less like a broken game and more like a system stuck in a loop. Underwater worlds repeat endlessly. Coin Heaven becomes a death trap and entire sequences reset again and again. Beneath the WORLD counter, something strange begins to appear…A blue-and-white item block that's assembling piece by piece. Almost as if the game itself is signaling completion. This isn’t just glitch footage. This is an investigation into how Super Mario Bros breaks when pushed far beyond World 8.
