Adapter
You will need PS2-to-PS3 memory card adapter to connect the PS2 memory card to your PC. Because the adapter uses a USB cable to communicate with the PS3, this USB cable can also be used to communicate with a PC.
Connecting
Insert your PS2 memory card into the memory card slot on your PS2-to-PS3 memory card adapter. Then connect the USB end of the adapter to an available USB port on your PC.
