Hackers jailbreak permanent mods onto Super Mario World save files


The practice of hacking standard Super Mario World cartridges on stock Super Nintendo hardware has come a long way in a short time. Three years ago, it required a robot entering thousands of button presses per second to insert arbitrary code on top of the game. By last year, streamer SethBling was proving that this kind of code insertion was possible for a human acting with pixel-perfect precision. Now, SethBling and others in the SMW hacking community have taken things a step further, permanently writing a full hex editor and gameplay mods onto a stock Super Mario World cartridge using nothing but standard controller inputs. SethBling’s ten-minute video explaining the entire “jailbreaking” process is a must-watch for anyone interested in the particulars of perpetually altering a 25-year-old game without any special hardware.
