# Photo!: reconstructing Game Boy Camera sensor and transfer behavior

> Photo! extends Game Boy Camera behavior in a replacement ROM using sensor rules assessed from MAC-GBD communication logs. It exposes manual sensor controls, changes printing speed, and defines a fast image transfer exchange using the standard printer INIT packet followed by a 0x10 packet carrying 3,584 image bytes. The source includes Game Boy and Game Boy Color builds.
