Super Mario Bros.
Arbitrary Code Execution Glitch Discovered: A Milestone for Retro Speedrunners
For over four decades, Nintendo’s Super Mario Bros. has cemented its legacy as a landmark in video game history.
Praised for its innovative level design and enduring gameplay, the original title and its sequel, Super Mario Bros.: The Lost Levels, continue to captivate players and the thriving speedrunning community.
Now, over 40 years since its debut, a groundbreaking technical discovery heralds a new era for retro game enthusiasts: the identification of an Arbitrary Code Execution (ACE) glitch in the original Super Mario Bros.
The recent resurgence of interest began when Twitter user @LuigiSidekick stumbled upon a crash while playing Super Mario Bros.: The Lost Levels.
As reported by Polygon, this crash turned out to be the result of a deeper glitch—one that unlocks the potential for Arbitrary Code Execution.
ACE, in game development and speedrunning parlance, allows players to manipulate a game’s code in real-time, effectively ‘reprogramming’ the title during gameplay.
This opens the door to unprecedented feats, including accessing hidden levels or achieving effects never intended by the developers.
Recognizing the significance of the find, acclaimed speedrunner Kosmic coordinated a focused research effort to determine if a similar vulnerability existed within the original Super Mario Bros. on the Nintendo Entertainment System.
Their meticulous investigation bore fruit: ACE is indeed possible, though setting up the exploit is remarkably intricate.
In discussing the discovery, Kosmic clarified to Polygon that “the true accomplishment lies in proving the concept and overcoming the technical challenge,” rather than obtaining a practical tool for speedrunners.
As he states, executing the ACE glitch currently requires more time than simply completing a traditional playthrough.
Nevertheless, Kosmic emphasized the achievement: "Ultimately, the meaningful part is the realization that it can be done and the puzzle it represents.
This breakthrough enables players, without any hacks or external tools, to access any world or level in Super Mario Bros., not just the famous Minus World.
It’s a demonstration of what’s technically possible within the game’s original constraints."
The impact of this discovery stretches beyond individual accomplishments, fueling further research into the technical boundaries of classic Nintendo software.
For the speedrunning community, such milestones represent not just new ways to play but fresh avenues for understanding and preserving gaming history.
As Super Mario Bros. sees ongoing availability through platforms like the Nintendo Switch Online service and the eShop, these revelations ensure the game remains a subject of fascination and innovation for generations to come.
This ACE glitch discovery adds yet another chapter to the storied history of Super Mario Bros., underscoring both the dedication of its fanbase and the enduring appeal of Nintendo’s platforming masterpiece.
