So. About 6 months ago I hacked my Guitar Hero for Wii.

It was actually pretty easy to do since the Guitar Hero Guitar just plugs into the extension port of the wiimote. There has already been a lot of "research" on communicating with the wiimote on the computer. All I had to do was start from there, look at how they parsed out the nunchuck extension, and port that to read what the Guitar Hero guitar was doing.

Anyway, it turns out we get all 5 button states (obviously), up strokes and down strokes (separately), and 11 degrees of movement of the whammy bar.

I took this info and fed it into my handy synthesizer as I played and turned it into a sort of instrument. My keyboard has a pretty decent electric guitar sound, so it sounded sort of realistic. I used the wiimote's orientation and the whammy bar to add different "note banks" to let me play more than 5 notes.

I posted this on youtube and got a (mostly) good response from it. Although apparently I'm a fag... and look like Harry Potter... and should buy a real guitar cause that'd be easier. Even though I play real guitar (and you can see them in the video), and have a girlfriend.

Anyway, the video:

A "tutorial" will hopefully be coming soon.
