Mario Kart 64 with a Wiimote on Computer

Andrew

So instead of being a good student and doing my calculus homework this weekend, I learned how to hack a wiimote and wrote a script to play Mario Kart 64 on it. I plan on writing more scripts for other games/applications/uses soon. Some thoughts are a way to use the wiimote as a wireless controller for media functions on my computer (i.e controlling iTunes, internet T.V, ect).

Here is the video

Ok, that's cool, but I have a more challenging task in mind. Write a program for the computer that will trick the Wii itself into thinking the computer with Bluetooth is actually a Wiimote! Then you can do all sorts of crazy stuff. Control the Wii with the mouse and keyboard would be the tip of the iceberg. You could save and load infinite Miis from the Wii to the computer. You could also write scripts to do speed-runs of Wii games. Speed-runs are going to be very interesting on the Wii because of the incredibly dynamic and imprecise control scheme. This will be the key to getting the fastest possible times in games like Monkey Ball and Excite Truck. Heck, you might even be able to make Monkey Ball playable.

Write a program for the computer that will trick the Wii itself into thinking the computer with Bluetooth is actually a Wiimote!

It already does that. Right now when I connect my wiimote through the bluetooth link several things occur. First off when queried by the SPD the Wiimote reports back tons of information. Here is the list of all the information that the computer recieves though the bluetooth connection. What is nice is that the wiimote follows the Bluetooth HID standard, which is the same standard that mice and keyboards use. If you want detailed information on how it works you can look at Wiili.org. While I haven't quite figured out how they got the low level communication working, I'm going to be going through the source code of the Windows applicaiton which emulates keyboard, mouse, and joystick listeners for the bluetooth connection and figure out how it takes the code and converts it into stack to communicate with the wiimote.

Does it now? So you can play Wii games on your Wii using your computer as a controller and not a Wiimote?

I misunderstood the question haha. I haven't tried it seeing as how I do not actually have a Wii, just a Wiimote. What one would have to do is figure how the wii's bluetooth drivers work and then fool it into thinking that the computer itself is an actual HID device, not a bluetooth hub.

Yes, I know what you would have to do to make that work. I think what you have to do is read

[Edit] I just managed to get this to work myself with little difficulty. Did you really write the script? Because with GlovePIE, it includes a similar, Excite-Truck like control scheme for MK:64. There is also a script for controlling iTunes and Half-Life 2. Check out what is in there so as not to duplicate a game and waste your time.

Anyway, I've found what I'm going to be doing with my Sunday!

Here is my script. I had a problem with the included MK64 script in that it crashed GlovePIE when I ran it. My new script also allows you to have up to four players to play. I also looked into Scott's idea and it sounds like no one has attempted it because it's too hard. Sounds like a project for my friends and I this semester ^_^

The included one crashes for you? Hmm...weird. But I like your script better anyway =D
