Just checked it out,it doesn't "do" anything.It's the default option file.In fact,there won't be a option file or a patch in the near future.The only thing that's actualy out for PES 2008,are the English team logos,you can download them here: (registration required)
Code:

There's also a readme with instructions to import the logos
cheers all
