which cd's are beening used?
and which program?
ive have the boot disc and a few games but want to make back ups of these?
you can just copy them and play them with the boot disc
you can't just copy DC games. The games use a special bigger gd-rom disc. The groups that release the games use special hardware to extract the images. You'll just have to find a dealer that sells DC backups.
There are sites (probably IRC) where you can find the images. A couple of friends of mine put them on regular CD-R's and distribute from there.
