How can I copy Twilight 40? (inside!)



I would like to know what kind of protections are on TL40 and how I can crack them!
When I’m trying to copy the original CD1 to my HD, very much errors appear on my screen.
CD2 isnt giving any visible problems!

btw: I cant install System shock 2 and Tournament Warriors from the ORIGINAL cd.
Can this be the problem?
The CD doesnt look damaged!
