Hi there,

I think some softwares (and protected games as well) use own data format 
what can be represented only with raw bit flow. The question is what level 
of compatibility is required.
The problem is to get an exact phisycal copy of the disks you need a 
modified drive with hole sensor, extra RAM and special software.
