A group of developers has reverse-engineered the Nintendo Wii U GamePad, peeling back the layers to discover the methods by which the controller connects with the main Wii U console.
Speaking to Eurogamer, developer Pierre Bourdon noted
, "The GamePad is actually not a very secure device... The device firmware is stored in an unencrypted Flash, which allowed us to reverse engineer the binary code pretty easily."
Since the GamePad communicates via a variation on the 802.11n wireless networking standard, this meant that Bourdon and his team were able to simulate the GamePad on a PC, as shown in the above video.
It turns out that the GamePad's controller inputs are sent to the Wii U console 180 times a second. An in-depth look at the logistics can be found in the Eurogamer write-up
