The original Nintendo DS included a small birthday surprise in its system settings, where players could enter their date of birth. When the console was switched on on that date, the familiar startup sound was replaced by a celebratory birthday version, turning an everyday boot-up into a personal greeting. Fans later ripped and shared the short clip on soundboards, where it became a favourite for birthday edits, reaction videos and retro gaming content that leans on early handheld nostalgia.
