[Hasuky] posted a guide for turning a PlayStation 3 Sixaxis controller into a PSGroove exploit device (translated). Unfortunately you’ve got to crack open the controller and add some parts to get it working. The hack requires a PIC 18F2550 (a chip we’ve already seen used as a standalone PSGroove device), a crystal, and various resistors and capacitors to connect to the controller’s PCB. From there you connect the USB cable between the controller and the game console and boot using the exploit.
