Super Mario 64 was first shown in playable beta form at Nintendo's Shoshinkai event in 1995, a year before its Nintendo 64 launch in 1996. Early footage and assets from that build, including different sound effects, later circulated among fans through recordings, ROM research and preservation projects. The beta footsteps became a small but persistent detail in that community, shared in comparison videos that highlight how the final game changed. It remains used because it instantly signals an early, unfinished version rather than the polished release most players remember.
