After you extract the folders put the 'PS3' folder in the Root Drive of your USB and the also the 'MUSIC' folder into the Root Drive of your USB. The important thing to remember is that it should ALL be in CAPITAL letters.
Hope this helps.
I have some troubles in adding the mp3 to the game.
1) I create a playlist named KONAMI_PES in my Ps3;
2) Then I insert my USB and I put all the chants in the created folder.
3) But, once I try to add chants to the teams (in the pes 09 editing mode) it doesn't find anything!!!
What do I make wrong?
