Show HN: After a decade of reversing, I got co-op working in DOS Wing Commander

A developer successfully implemented cooperative multiplayer for the classic DOS game Wing Commander after a decade of reverse engineering by identifying player and wingman coordinate data in the game's 640K memory space. By taking memory snapshots of the game in different states—stopped, moving in different directions, and in empty space—the developer was able to narrow down which bytes controlled character positions from over 1 million to just 253 bytes. This discovery enabled network packets to control the wingman independently, allowing two players to fly as separate wingmates rather than controlling a single aircraft together.
