Adding files to a .img

Does anyone know if there is a way to add files to a .img that was created from a cd.
Example…I created a .img of Diablo II Expansion that I know works, so I was wondering if I could add a .txt file with he CD Key and also the latest update patch for LOD…does anyone know, any help would be much appreciated.

You can try this little tool and see if thats what you are looking for.

VB9999 :cool:

I think you can modify the image of protected CD with tools like CDMage or WinISO, but the game won’t work properly.

Diablo 2 LOD is SECUROM protected - modification of *.sub is also needed, but how?
