The Japanese gaming giant apparently created the device as part of the promotion for a remastered 20th anniversary re-issue of Parappa the Rapper, a title based on a rhythmic rapping dog.
According to SlashGear, it’s dubbed the “Deca Controller” being ten times the size of the original. Size isn’t everything, however, the website notes:
Only half of the functionality actually works, namely the four buttons, the D-pad, and the L1 and R1 buttons. The two analog sticks and the L2 and R2 are just for show, though they may feel functional.
