CD-Copy Instructions:

Create the following temporary directory: 
TempDir :  C:TEMPCD 
Copy the full contents of the original CD to TempDir. 
Extract the Executable Archive (Oni_cd_copy_UK) to TempDir. 
Extract I5Comp v2.01 to TempDir. 
Execute ONI.BAT from the TempDir to replace the game executable in the installation files (DATA1.CAB).
The batch file will also remove the I5Comp files as they are not needed to play the game!
Burn the contents of TempDir to a CD-R and use the same CD-Label as the original CD. 
Remove/Clear the TempDir. 
Play the game!
