Things You'll Need
Instructions
Obtain a flash drive and copying software that works on your PS2. MaxDrive is an example of software that can be used. MaxDrive says only its flash drive will work with its software, but any one formatted the same will work.
Format the flash drive so it will copy from your PS2's memory card. Plug the drive into your computer and run a format tool. Select the "FAT" or "FAT 16 File System," check off "Quick Format" and click "Start."
Insert the software disk into the PS2 console and plug the flash drive into one of its USB ports. Then start the console.
Follow the instructions on the screen telling how to copy saved games. This likely involves going to a "Devices" menu and selecting the memory card choice, picking a saved game from a list and selecting "Copy to (flash drive)."
Run the same software and plug in the drive to transfer saves to the PS2. This time, select the USB drive as the primary device, select a save and select the choice to move to the first memory slot (it may use the word "uncrush.")
