Ah well, you're determined to be right so you win. I think you'd get another input out of the tilt sensor, too.
It was just something I had contemplated as I've seen people throwing these controllers away, and hauled one out of the trash last week...
I'm not just determined to win. I am also right. You are guessing as to what is there, while I know exactly what is there.
Green = A
Red = B
Blue = X
Yellow = Y
Orange = RB
Whammy = right analog stick from center to right
Tilt = right analog stick pushing up
Strum Bar = d-pad up & down
5 way selector = various positions of the left trigger
Back, Start, Guide and D-Pad are all self explanatory.
On a rock band guitar the solo buttons are the same as the regular buttons with the addition of having the left stick click pressed as well.
If what it offers sounds sufficient for you to use as a hack for an arcade setup, then by all means go for it. I was simply stating its limitations.
[EDIT]
I notice that I stated in my other post that the strum bar was analog stick. That is incorrect, and what I have in this post is correct.
Oooops
