How about trying to mount the isos at a virtual drive and copy the files in the cd to your ff7 directory and run the game so that you'll do not need to read the files in the cd instead. If the files in the cd itself is destroyed then yeah go buy the game again. You have the money anyways.
Isn't that illegal?
not illegal to make iso's of your own disks IF you own it, its illegal to put them out for download, and illegal TO download, but if the files are destroyed by scratches, the iso won't work
That's the same thing as saying it's legal to copy music from a CD to your hard drive or to iTunes. In some countries, this is illegal. Therefore, copying the game from the CD to an ISO is also illegal.
In some countries, yes. But in most English-speaking countries at least, it's perfectly legal to make backup copies of your own things, as long as you don't share them, and don't have to get past any DRM or antipiracy software to do so.
And legality aside, I think most people wouldn't see it as morally wrong, and it's virtually impossible to catch or prosecute.
