Jailbreaking Super Mario World to install hex editor, mod loader

Cooper Harasyn found a Super Mario World save corruption glitch, and we worked together to create a jailbreak that works on real, unmodified cartridges and Super Nintendos.

They managed to install a hex editor and a mod loader onto unmodified Super Mario World cartridges running on unmodified Super Nintendos. With the mod loader, you can, for instance, give Mario telekinesis powers. This is somewhat reminiscent of a similar extraordinary feat in Castlevania: Symphony of the Night we talked about earlier this year.
