the icade's input devices include an 8-way ball-top joystick and eight digital buttons. when placed inside the icade, the ipad is positioned vertically, while a groove behind the inputs accommodates landscape-mode play. on the front of the device is a "coin slot", which lights up to show that the icade is powered on, and flashes when its batteries are running low. power can be sourced from either two aa batteries or an ac adapter. it is also possible to run an ipad docking cable through the underside of the icade, in order to charge the ipad during play.
