SafeDisc 3.15, 3.20 and beyond are getting harder & harder to beat. Quite often, with Alcohol 120%, I can make the image files (MDF/MDS or ISO files) successfully and when I mount the image files to virtual drive, I can install & play the games without problems. This gives me an impression that I have got perfect image files. So, I go ahead and burn the image files to backup CDs. With the backup CDs, the installation runs smoothly. But, the games installed from the backup CDs refuse to run. Its is a conundrum to me why the image files work but the backup CDs do not. Well, maybe my CD-RW drive is not good enough (Sony CD-RW CRX215E5). Are there any other reasons? Could some experts out there please shed some lights? If the image files work, can I simply burn the image files as data files to backup CDs and then, mount the image files from the backup CDs to virtual drive? Will that ever work? Let me use an example to illustrate the problem. Say I just bought a game named "foo" (the game contents are not important for this discussion). It has three CDs. The first CD is carrying SafeDisc 3.20 protection. My goal is to backup the game so that I can save the original CDs and just use the backup CDs to install & play. I launch Alcohol 120% to make three image files in my hard disk --- foo_1.mdf/mds, foo_2.mdf/mds and foo_3.mdf/mds, all with "SafeDisc 2/3" profile. I save three original CDs to somewhere as I am not going to use them any more. Next, I want to verify the image files. I mount foo_1.mdf/mds to the virtual drive. Run setup.exe/autorun.exe/launch.exe or whatever from the virtual drive to start game installation. Naturally, during installation, when I am prompted to insert disc 2, I simply unmount foo_1.mdf/mds and mount foo_2.mdf/mds to the virtual drive. When I am prompted to insert disc 3, I simply unmount foo_2.mdf/mds and mount foo_3.mdf/mds to the virtual drive. When the installation is about to terminate, I am prompted to insert disc 1 again and I simply unmount foo_3.mdf/mds and mount foo_1.mdf/mds to the virtual drive. The installation ends successfully. I am able to launch the game from the virtual drive and play the game without any problems. Next, I want to burn the backup CDs. I unmount foo_1.mdf/mds from the virtual drive and uninstall the game. Then, I launch Alcohol 120% to burn three image files to three backup CDs. Then, I use three backup CDs to re-install the game. the installation ends successfully. But, when I try run the game, it refuses to run. I don't know why. Next, I am thinking, since the image files work, maybe I can just save them as data files to backup CDs. So, I launch Alcohol 120% to remake three image files --- foo_1.ico, foo_2.ico and foo_3.ico. This time, they are in ICO format instead of MDF/MDS format because one MDF/MDS file typically does not fit into a single CD but one ICO file does. Then, I launch regular CD burning software (RecordNow! which was pre-installed when I bought the PC) to burn foo_[1|2|3].ico into three separate CDs. Note that, here, foo_[1|2|3].ico are simply treated as data files. Next, I want to try backup CDs burned this way. I first put the CD containing foo_1.ico file into my CD-ROM drive (say, E drive). Then, I mount E:foo_1.ico to the virtual drive (say, L drive). From L drive, I now can see everything in the original CD 1. So, from L drive, I run setup.exe/autorun.exe/launch.exe or whatever to re-install the game. But, the installation does not go well. When I am prompted to insert disc 2, I meant to unmount E:foo_1.ico, insert the CD containing foo_2.ico and mount E:foo_2.ico to the virtual drive. But, I was unable to do. My PC somehow hands up. Am I doing something stupid here? I was wondering, will backup CDs burned this way, i.e. treating foo_[1|2|3].ico as data files, ever work? If this approach can be made to work somehow, what it means to us is that, to beat SafeDisc 3.15, 3.20 and beyond, we do not need heavy-duty burner (the image burning part of Alcohol 120%). We just need good-quality image maker (the image making part of Alcohol 120%). Your comments and suggestions are highly appreciated.
