Hi, I've got a number of games for which I like to keep a backup copy of the CDs at the office. This saves me having to drag around the CDs and forgetting then in one place or another when the fancy strikes me to play. So far so good. This has always worked.
If you're talking about backing up copy protected windows games... do it in windows. I know of no linux cdrecording software that properly reproduces subchannel data.
Am I dealing with copy protection, or is this something else?
Probably.
I'm just using
mkisofs -o EXILE_DISK_1.iso /mnt/cdrom
This just records the iso9660 image. The concept of subchannel data is missing.
which seems simple and straight forward, but maybe it's not good enough?
There are a ton of options to mkisofs. Do I need to try some other specific
ones?
In addition to copying the subchannel data, you need to get the burning software to reproduce it. Windows has clonecd and other software... linux has no need for this. I guess if someone felt like writing it they could, but I really dont know where to get docs on how to properly implement it.
If you have no clue what I'm talking about when I refer to subchannel data, look here:

It should be noted that not all cd-r's can reproduce this data.
