Need help playing BackUp from HD *INSIDE*

[CitizenX]

OK here is the prob. does anyone know how to bypass needing the CD after i rip my original game to HD, after setup and when i execute game it does a CD check and asks for it. even though files are on HD. What files do i need to modify to go around this? or what software do you reccomend to make or patch this. Any Help would be greatly appreciated.

Thank You
