I have a question on copying FF9

[Buggy]

Ok, I got this original copy of FF9 from friend.

And I extracted all 4 cds of them to bin/cue using CDRWIn.

But someone told me I must patch before I burn them to CD.

Can anyone please explain this kindly and details to me?

and also Is the graphic or sound quality is going to be not same as the original game?

Thank You.
