Ok, You must first make a copy with another copy prog or with alcohol and setting on securerom ,etc... emulation. Mount the iso and compare the iso mounted with original CD (there're lot of programs to do it). You must analyze 2 things, a) There is not error copying original CD (can be fake sectors like I said in last post and then you must change your procedure) b) Are exactly ISO and original CD. Then mount ISO and debug. Before to work debugging ensure steps a) and b).
You can use gamejack better than alcohol, play with the settings in both progs.

welll if there was one i think that every app of burning would have done it for you and then fix the image .. i don't know any application that can tell me this info

Then mount ISO and debug

if the iso is a perfect image and fixed so why i need to debug it ? it should run like the original... (meaning : won't ask for original CD)

That is not right If you have a LiteOn drive you can use a very low level verify app. There're specialized apps to check CD integrity with its own low level driver. Some drives let you read hidden tracks. It's better to compare (generate a checksum, etc...) using Nero Disk Speed than putting verify on setting in your burning soft.

If the iso is perfect then your app reads CD manufacturer ID and other fields. Then you must debug CD API.

ok ...i didn't thought about this.....
i will look closer about this .. what do you recommend api to hook and trace?
DevicIoControl?

but still
If the Image is perfect, when app reads CD manufacturer ID it should emulate also the manufacturer ID no ?

DeviceIOcontrol & Createfilea. Like I said in a old post, use CDR Identifier or Nero's CD-DVD Speed/Disk Info and compare manufacturer ID with original and emulation CD. Another reason is that your app checks emulation soft and then refuse to run.
Can you upload to rapid or mega to take a view?
