This was posted long before me as well as I was writing this, but I'll rehash it with some new info as well.
Wired and Wireless - Guitar
LT - Green
LB - Red
RB - Yellow
RT - Blue
A - Orange
Bk - Star Power
Left Analog Stick Up - Whammy
D-pad U/D/L/R - D-pad U/D/L/R
Guide - Guide
ST/Bk - ST/Bk
The Wired/Wireless also have no strum button and the note is picked when the controller's button is pressed, as skorchir pointed all this out earlier. This makes adding in the Plectrum to keep the Guitar feel intact a new level for the fun as well as a good deal of rewiring on the neck buttons to conform to the controllers button's layout.
The Star Power is done on the Guitar with an Accelerometer or some other type of motion sensing IC. This can be duplicated with some other type of mechanical sensor (like the 360 uses to change the Ring of Light) to mimic that IC and push the correct button on the controller when the guitar is tilted.
This can still be made wireless, though you'll be doing a F-ton of work and still loosing some of what the actual Guitar is capable of, Hammer Ons and Pull Offs for one, and that craps all over playing the game on the harder levels, if that stuff is even in there with a controller connected. The Plectrum would have to be setup to close the button circuits when it's picked, that would let ya hold the note before hitting it, but wouldn't show up in the game that you were holding it until strummed, thus hitting or blowing the note(s) in question.
I won't be doing this mod at all now, just too much being lost or a real bear to translate over to a Wireless controller and the game is too much fun for me to have it all torn down figuring out this and that right now. If anyone else still wants to go for it I'll help out with Wireless controller hardware info and how I might go about this and that and such, and any updates or new things I may think off or find out post up in here, but I don't think anyone that gets the Wireless stuffed in there will be 100% happy with it unless it's completely ironed out to work like the Guitar does now. That's a shade more work than I feel is worth it for having it Wireless right now. As of now, doing this mod will just get you a Wireless controller shaped like a Guitar, instead of a Wireless Guitar. Plus if the Pedal comes out you'll be tied to the thing with that cord and then you're still not really Wireless.
P.S. Playing with the controller after using the Guitar SUX hardcore.This post has been edited by RDC: Apr 7 2007, 01:18 AM
