On Nintendo's official site, the company has announced a few games that would be compatible with the 3DS' new Slide Pad accessory; Kingdom Hearts Dream Drop Distance was amongst the group.

This accessory is used to give the 3DS a second circle pad as seen in regular console controllers. Perhaps this will help with camera use in handheld games which seems to be a common complaint amongst handheld buyers.

Still no word on when we can expect Dream Drop Distance, however, 3DS owners in Japan can purchase the accessory starting 10th of December.
