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?

Super Mario Bros just keeps getting stranger… and in Part 4 of the Glitched Worlds series, we explore Worlds 39–48 — where the cartridge stops pretending to follow ANY rules. We’ve got looping sublevels, underwater 1-1 copies, broken castles, unbeatable clouds, warp-less mazes, and multiple Minus World appearances… again. If you thought Part 3 was weird? Part 4 is where the glitch energy turns into full-on playground myth territory. This series documents all 256 Glitched Worlds found through the infamous Super Mario Bros memory corruption trick.
