how do u make a backup of PROJECT IGI
 

I would like to make a backup of PROJECT IGI but I am unable to copy the disk as it has some "dummy files".
Does anyone know what I should do?
I have the english version.
This is a legitimate request as I like to use backups rather than the original which I keep in case it gets damaged
thanx in advance

How to make perfect copy of Project IGI UK version

Project IGI is the piss easiest game I have ever had to backup. It has three protections to make it harder to copy but anyone can copy it.
1. It’s is an oversized CD.
2. It’s got a data then 2 audio then another data track. This is an illegal TOC.
3. It's got dummy files, they are hidden, and they have an .afp extension.
Make a image using clone CD
Read at 1 speed
Read sub channel data and audio
Write with everything tick except simulation
Write a 1 speed
Use an 80 min CDR. I used a Memorex CDR.
I did everything at one speed because there are fewer chances of errors and I’m tired of making coasters. And I read and write using a Sony 140E.
