Backing up to VirtualCD

[AlexRaven]

Hello everyone!
The problem is: i have a SafeDisk protected game-cd and want to copy it to my HDD to play it from VirtualCD.
1. i made a cd-image
2. used unSafeDisk to crack - result is unprotected .exe file
3. rename/added testme.exe to cd-image
4. converted image to .FCD

and ??? it doesn't work, keeping on asking for game cd, or hanging when i try to run the original executable.

What is my mistake? Any hints on how to handle this kind of situation?

P.S. I can download nocd pathes for peculiar games, make CloneCD 1:1 copy. But it doesn't solve the problem of playing games from HDD.

P.P.S. If this post seems too stupid - sorry
