USING THE WII U CONTROLLER WITH whatever
It’s been just a bit over a year because the Wii U was released together with the incredibly outstanding Wii U controller. With a D-pad, analog sticks, accelerometer, gyroscope, magnetometer, video camera as well as 6.2 inch touchscreen, this controller is ripe for a million as well as one jobs ranging from FPV quadcopters as well as robots to things we can’t even believe of yet. At this year’s Chaos communication Congress, [booto], [delroth], as well as [shuffle2] demonstrated exactly how they cracked open the Wii U controller’s encryption allowing for Wii U controller ’emulation’ as well as providing us full documentation on exactly how the whole thing works.
The men started on their reverse engineering journey by disposing all the flash chips discovered on the controller’s board. In those binary blobs, they discovered Nintendo utilized a really ingenious method of obfuscating the WiFi secrets utilized to link the controller to the Wii: rotate left by three. To be fair to Nintendo engineers, it was protected up until somebody figured it out.
Connecting the controller to a PC over WiFi is only half the battle, though. preliminary info from the Wii U introduce suggested Nintendo utilized Miracast for all the I/O between the controller as well as the console. This isn’t the case; instead the video, audio, camera, as well as button input are non-standard however extremely easy protocols. The hardest to break into was the video screen for the touchscreen, however the men found it’s quite much H.264. After getting around some Nintendo weirdness, it’s possible to screen video on the controller.
The men have put together a small, incredibly alpha library that includes all the demos, documentation, as well as reverse engineering information. There’s a big desire listing of what this library ought to include, however now that the info is public, it may be the time to pick up a Wii U.
Video of the talk below, here’s the presentation slides, as well as a demo of emulating a Wii U game pad on a PC.
