Does anyone know how I might be able to create a pad with a few characters that connects to a normal keyboard for games?
Thanks,
That will work perfectly, I never thought of looking up Guitar Hero.

Here is a tutorial I have used in the past::

You have to download a program but its free and works as advertised.

It'll move like the DIY Mouse and have the buttons of the arcade mouse. I'm confused as to how the buttons on the mouse and dance pad will hook up to the keyboard. What I wrote above I thought people would be more likely to know the how-to, and I could just enlarge it.
Thank You.
PS: Maybe I'll make an instructable of my amazingly awesome machine?
