Is it legal to use controllers, especially the xbox 360 controller, during the competition other than the ones given in the KOP.
Legal? Yes. The DS works with HID joystick type devices. If Windows doesn’t recognize the device, install the drivers that allow Windows to treat it as an HID.
As Greg said, it is legal, and I assure you it will work, since we’ve been using that exact controller for the past two years.
The wired Xbox 360 Controller is legal. The wireless one is not.
