Installation Guide:
Create a number of folders on a device suitable for transferring data to your console.
The folders should look like this:
PS3 - then inside it these folders - SAVEDATA,MUSIC,VIDEO,PICTURES
Copy the files you want to the MUSIC folder.
Insert your device into your console then add to 'KONAMI_PES' playlist folder (if the playlist folder does'nt exist, create it then add the files to it, otherwise it won't work in Pro Evo).

Hope this Helps!
