Hi all! I have ps2 77004 with modbo 4.0 installed. Chip works very good, but there is problem - when I turn "PSX MULTI DISK" option ON in the service menu to play multi dics games, console's laser/drive begins to make strange knocking sounds and read discs worse, than without "PSX MULTI DISK" option. Resoldered this chip and it didn't solve the problem. Could it be a bad laser?
