Well I had a PS2, and I also had DDR Supernova and 2 PS2 mats. Now Ive had my PS3 since Xmas and havent made my PS2 since then and I need some help with an adapter for the mats to plug them into the PS3's USB ports. Has anyone else done this? If so could you lead to me to the exact ones you used that worked good for you? Thanks
