Maybe someone could help me

. I used cloneCD to copy one of my favorite games to hard drive, because i fear that i will scratch the disk. CloneCD is the best CD copying software i have come across, however i am disappointed that the software doesn't compress images well. Does anyone know of a utility that would compress this image yet keep the image available to cloneCD?

Clone CD does not compress images - as far as i am aware of, it makes an ISO image, there is no specification in the ISO9660 that calls for compression. (edit: according to one site, CloneCD does not make valid ISO images)
If you compress the ISO image, it will not be readable in cloneCD. I am not aware of any programs which offer ISO compression. Why? It would not be an ISO image then, it would be an ISO in a compressed format, such as a zipped file. If you are aware of any program which offer on the fly decompresion of a compressed image, drop a link.

Otherwise you would either have to use an external compression app. such as WinRAR, WinACE, Gzip, or Bzip. which would require decompression when you want to use the ISO image again.

You could make an ISO image of the CD, then compress it, this would permit you to copy that compressed file to a cd for back up purposes. I have many operating system which i have grouped together in bz2 format, and i store them on a CD. This way i am able to keep several backup images on a single CD.

Did find something that might be interesting for some, wont work for CloneCD, not sure if the project is even still alive. Most likely will only run under a *nix OS. But may work under MS Windows via Cygwin

Iso9660-compr This project aims to provide a transparent compression scheme for ISO9660 (the format used on CDs), to be able to store larger amounts of data on a CD, providing the user with the illusion of a larger CD, instead of a CD containing many compressed files.

I had a program a long time ago that i used to use for playing games that i copied onto my HDD from a CD but i can't remember the name of it or from where i got it. The only thing i do remember is that it was a DOS program. If anyone knows what kind of program i'm referring to i would really like to get it again.

You can create CD images, that play from a "Virtual CD drive."
Sometimes you can compress the VCD image and it will work.
sometimes it wont. mostly for games and such, that are super sensative to how the CD is actually created. I have had some that worked, but Halo PC ® ™ wouldn't work until I changed some settings around.

It isn't a DOS program, and I probally isnt what your looking for, but is better than nothing. Hope this helps.
