I just created an image file using Nero, but before burning the image into a CD-ROM I need to edit a single file inside the image. I just need to open the .NRG file and change one file thatÂ´s inside for another one. But how do I do this? Is there a program to make this kind of work? I just downloaded IsoBuster but it seems it only browses and extracts the files inside the image file.
