It's hard to explain with all the various different formats. There is going to be one huge file, that is the actual image. The rest are usually descriptor files, they describe what tracks end where and whatnot. You will usually need them, I believe, for the ones that have more than one track on them. Like the ones that have actual CD audio will have the one data track with the game, and then the music tracks. You have to make sure your PS2 is modded, as well. But yea, you can use those to make the CD, and it will essentially be just the same as copying it from the original (unless they ripped some data from it.. but that isn't often).
All I can say is that my life is pretty plain
I like watchin the puddles gather rain
And all I can do is just pour some tea for two
and speak my point of view
But its not sane..
I just want some one to say to me
Ill always be there when you wake
Ya know Id like to keep my cheeks dry today
So stay with me and Ill have it made
And I dont understand why I sleep all day
And I start to complain that theres no rain
And all I can do is read a book to stay awake
And it rips my life away but its a great escape..
All I can say is that my life is pretty plain...
