BCDM: NOKAMA's Disc Mark: The Great Disk of Ga-Metru is the Mini CD-ROM included with the European TOA NOKAMA set. The disc contains the same program, with some minor differences, that you can download from the KANOKA Club if you have entered a code from a NOKAMA KANOKA Card.
The adventure follows TOA NOKAMA as she seeks the MATORAN VHISOLA. Along the way, you are met with the usual challenges: a "Simon"-like sequence game, some "8 puzzles", and Pick-Up Sticks. These "8-puzzles" each have a slight twist in that the open space is in not located in its usual lower-right hand corner.
Although you might think there is nothing new here, NOKAMA's adventure is the one official source for the six codes of the Great Disks. One of those codes opens up VHISOLA's safe to reveal the Great Disks' ultimate secret.
The program ends, as all of the TOA METRU adventure programs do, with a little menu for viewing videos or connecting to BIONICLE.com:
