Field notes
The site describes a record for each game that connects its source—such as a purchase, giveaway, or matched preservation-list dump—to a boot result. It says queued tests run on the machines themselves, which launch the game and return a recording. The homepage's example library reports 68 systems and says its figures come from its Status, Shelves, and Results pages.
