Is there a way to find out the code to the box in the corner of the Akuda Bar near the disk game?

Sure,but you must have all pearls and all species.Then register to the Darkroom on Official BG&E site and type in Savegame Internet Code.Then try to make the first mission.If you do it well,you'll get code to this box as award :)

(To be honest,nothing much is on this M-disc...)

Ahhh much thanks! I need every little item in this replaying of BG&E that's possible!

But then all you can do with M-disc on this box,is just beating scores on Most Wanted list of best BG&E players on BG&E website...If you wanna,dare others!

So this is the MDisk I never got! Thanks.
