Welcome, puny fleshling. SM64.org has since 2009 been the primary site for Super Mario 64, especially tool-assisted play (using emulator tools like save-states and frame-by-frame recording). We have a discussion forum and a wiki where we keep track of records and information about the game. We host competitions in a dedicated subforum, and anyone is welcome to participate.
