Can you use some sort of PS2 management utility or PS2 media player which allow you to organize file in your memory card, transfer file from mem card to USB Thumb Drive, access HDD through USB port to transfer GT4 save to USB thumb drive as a back up? (program such as "MyPs2" if i remember the name correctly)
I tried to access memory card through this program but it displayed all sort of folders with names that I could not make out what they are. Anyways copying GT4 save to USB thumb drive by using this type of program will certainly save me from buying extra PS2 memcard or the costly USB max drive.
Cheers!!!
