They used the Super Mario World leaked code to figure out which synthesizer sounds were originally used by Koji Kondo when he composed the game soundtrack.
They did deep investigation to figure out which synthesizer Kondo used at the time and pieced together which sounds were the correct ones, based on file names and other information we know from Kondo's life at the time.
