Strange Backup CD

[COPIER]

Hi all,

After 3 days i just managed to make a copy of NOLF using CloneCD 3.0.6.1. I also used Beta blocker to patch the safedisk protection. Anyways when i started to play the game i got this horrible stuttering/echoing sounds during playback f.e. firing. Is this some other sort of copyright protection or is it to do with the settings of clone cd? Please help! Thanks
