Nintendo’s Satellaview, a Japan-only satellite add-on for the Super Famicom, is a rich target for preservationists because it was the home to some of the most ephemeral games ever released. Remarkably, the 10 courses in those later broadcasts were reverse-engineered, using a VHS recording, machine learning tools, and some manual pixel-by-pixel re-creation. Using Graphite as inspiration and having the data from the original Grand Prix broadcast as a baseline, an F-Zero superfan going by Guy Perfect built a tool that could reproduce the controller input from a miraculous VHS copy of the missing second Grand Prix.
