Final Fantasy IX

[Necos]

I just bought FF9. I didn't want to ruin the original cds, so I sought to make a backup. I powered up Padus Discjuggler 2.0 and imaged all the cds. Then I went ahead and burned all of them. Everything was fine. I go to test them in my mod'd 5501 and nothing... Does anyone know if this game has mod detection or some sort of other protection I didn't know about. I'd appreciate any info.
