Trying to copy EA PS2 games with CloneCD

[MarkyMark]

Quick question,
I've got a moded ps2 with the usb mod. I've been able to play other copied games but I've not had any success with backing up EA titles such as Tripple Play or Madden. I was wondering, is it possible to copy these games with clonecd? Do I need to do something different? If there is another way, please let me know. Thanks in advance for your help.
