backup help

I need creating a ps2 backup, i have tried using numerous programs: dvd decryter, alcohol 120%, nero, primodvd and I can't get it to work. The game i am backing up is Wolverine, I am using a dvd+rw to test out this back up to make sure it works before I put it on a dvd+r. I have a version 7 ps2 with a magic 3.6 chip. Can someone pleas help me?
