How do i use a PS2 saved game on a Backup?

Load up the uLaunchELF disc in your PS2 and plug in your USB drive. This CD should work in any PS2 capable of playing ‘backup’ discs, if everything goes to plan you should see the PlayStation2 logo for a second, followed by the uLaunchELF menu. You should see a list of drives, including the PS2 memory card(s), and hopefully your USB flash drive (listed as “M”).
