1) Go to http://www.gamefaqs.com/ps2 2) Click on the first letter of the title you want (if i want a game save of Metal Gear Solid 3: Snake Eater, then I would click on the letter M)
3) Scroll down the list until you found the game you want.
4) Click on "Save" in the right (NOTE: If it doesn't say "Save", then that means they don't have the save file. Sorry)
5) Find the game save you want, and click on "Save Game File" (WARNING: Make sure the game save you want is the same region your game is. A European game save will not work with an North America game.)
6) And it should download automatically.
I already tested the program with a game save for Metal Gear Solid 3: Snake Eater, and it worked. And I'm NOT responsible if the game save you download wasn't really what it says in the description. For example, if it says that the save its in the last level. But it's in the 1st level instead,
