ok thanks a lot. Clone CD worked, I burned a CD, and played one level of one of the WADs.

I guess if you know what they mean, the file extension says it all, CCD = Clone CD. But I didn't know that.

thanks again,
Ron

I downloaded the Master Levels for Doom 2 from this site, the ISO version. After downloading, I ran WinACE and it created a file named *.img, about 400 Mb, and two smaller files. Now what do I do?
