Hi, I'm new at this and I need some help. I have a ps2 (SCPH-39001) I believe is a v7. I tried to play pro evolution soccer 2007 online but it gave me a DNAS error becuase of my mod chip, I been reading about the mod chips but my problem is that I do not know which one I have. I bought my ps2 whit the chip already installed and the only thing I found it was a mr5 sticker on top of two screws. I open my ps2 but since I don't know much about it I Stopped.To read the burned dvds I have to re-boot my ps2 twice. Can some one help me please???
