I have a couple of old video games—The Hobbit (2003), published by Vivendi, and Zapper: One Wicked Cricket (2002), published by Infogrames—which won't boot when mounted using a virtual drive, but they do boot using the game CD in a real drive (not all old games have this problem). I thought virtual drives were indistinguishable from virtual ones. How can I circumvent this? I have already tried changing the drive letters, but to no avail.
I use Windows XP SP3 32-bit. I used CloneCD to create the images and VirtualCloneDrive to mount them. I have also tried WinCDEmu.
