Pad hacking - cheaper 360 Alternative possibility

This is just a theory hack for PC users but it seems like it would work but with some limitations.

Instead of gutting a controller for a second player on PC, why couldn’t you use a 360 chat pad for the PCB and plug it in to player 1 and map it all out on Xpadder?

The only question is the chat pad port fast enough for gaming inputs?

A Chat pad?

Would it work for Xbox 360, nope.
Would it work on a PC with Xpadder? Only if Xpadder can get to the the button presses from the chat pad.

You are far better off with a pre-made PCB like a Toodles Cthulhu as it registers on the PC as a HID game controller and requires no drivers to be installed.
