Okay, I found this odd madcatz device a few days ago inside a box for Guitar Hero 3. It has a female PlayStation/PlayStation 2 controller port on it as well as a momentary switch. It takes three CR2032 coin cells. When the button is pressed it outputs 9v of power on pins three and four (which power the rumble motors in the DUALSHOCK/DUALSHOCK 2.) Other than the Madcatz logo it has no other markings. Does anyone have an idea what this might do? I'll upload a pic if needed.
