Can you edit ISO files?

My sims 2 University disk isn't working because the ijl15.dll file is corrupted but I downloaded a working one, can I somehow put the non corrupted flile onto the disk? I mean the ISO file I created from it? Are there any free ISO file programs that can do this? all the ones I've downloaded don't allow editing under trial. Also I've downloaded the Alcohol 120% from the site and I made a virtual image, can I edit it and how if possible. Thanks

This sounds illegal.. How did you get Alcohol 120% for free? If you're asking if you can edit the Sims 2 game disk, I think you're out of luck. Those disks are pressed and not burned, so you aren't able to rewrite them.

I downloaded the alcohol 120 from this site. It is a trial version

If there's a corrupt file on your Sims 2 disc, then you should ask for replacement media either from the store you bought the game from, or directly from EA.

This sounds pirated to me

I'm not 100% sure, but to me is sounds like he made an ISO out of his Sims 2 disc, and then wanted to know if he could replace the corrupt DLL in the ISO image. I bet there are applications/programs out there that can do this without you having to pay for them.

Oh, I fixed the problem it was just the one file on the ISO file image I was using from the disc. I didn't even know this thread was still open...I need no more help regarding this got it solved: I'm using UltraISO.

Try using magiciso to make iso file of cd. It works well to me.
