Mdisk

An Mdisk is an optical disk in Beyond Good & Evil. They directly resemble CDs or DVDs, while carrying much of the same function. When played using an Mdisk Decoder, they have the ability to play messages from other characters or organizations in the game, storing digital issues of IRIS publications and in one case, CCTV footage. There is also a Game Save Disc that ties-in with the checkpoint system found in many other video game by allowing players to save their game once they reach an Mdisk Decrypter.
