Snake Eater Protection

I spent 3 dvd’s trying to backup my brand new copy of metal gear solid snake eater with alcohol 120% and failed everytime. Does this game have some sorta special protection ? If anyone knows how to back it up please tell me… Thanks !

Try scanning the disc with A-Ray scanner and it should tell you what the protection is, then let us know and we may then be able to help you.
