crazyc: to quote byuu from
this reddit, "there was no score uploading from the SNES to another machine, there was no networked play".
What did it do? "That connector was only used to feed status register bits. One of the bits activated a mode where each player got to enter their name, and then the system would wait. Once all players had their names in, the host could clear that bit and the game would start playing for everyone at the same instant. It ensures that everyone finishes at the same moment."
