The code for The Legend of Zelda: A Link to the Past has recently been reverse-engineered by programmer xander-haj. In the about page of his GitHub, the user reveals how they cloned the code and re-implemented it, producing a playable game from start to end. They claimed to have completed the process by using user spannerism’s Zelda 3 JP disassembly and others that recorded different variables and function names. Reverse engineering is a difficult technological operation, but it paves the way for unauthorised ports to other platforms with increased functionality, such as when a modder reverse-engineered the original Perfect Dark.
