Unlock Disc Mini-Game
For those of you missing the last mDisk, it is in a locked item cabinet on the Akuda Bar's first floor (by Francis' table).
To get the code, you will need to register on http://darkroom.ubi.com and enter your sixteen character "save code" (this code is generated each time you save the game) to receive the four digit code for that cabinet (it will depend on your game statistics).
Unlock Marble Mini-Game
Get all 88 pearls and a marble mini-game on an mdisk will be available.
