You may be able to use CloneCD to rip the GC disk - not tried it yet though.

I don't think having different setting is gonna make a difference when it comes to reading a disc when it won't even load..
If it loads I could see a possibility but it doesn't load so no software in the world is gonna make a difference..
This is little off the Subject but In order to make a 1:1 backup of Gameshark Disc you need to use Blind write program which reconfigures the some of the CD rom setting software wise which reason why it's able to read after installing it otherwise back to Zero with blinking lights meaning not reading the disc..
