HI
first you can use discjuggler to read cd to image then, you can cut out with cdirip , if the game is selfboot you have to files 1 track audio
and bin , for the 1st session u can use fire burner , then for the second session u can use cdrwin to burn iso image finalize , mode2
or u can use CDI TO NERO , it's a simple way

remember to cut out 2 sector , because your cdrw can't write 300 sector track audio .

that's all
