are these only working with europe releases of games? i have only usa release and i can not get it to work for anything. i am putting the covers folder into the OMAN4567 folder and then the .PNG into that folder. do i need to make a folder inside the cover folder for each game? for example, i am trying to get it to work with castlevania and i tried naming the game folder BLUS30339 and the picture BLUS30339.PNG. does the game folder also need the .PNG inside it or what am I doing wrong? any help would be appreciated.
