Myst III Disc 1 wasn't able to be copied and is using safedisc2. But then the Myst III 1.2 patch came out about the same time as the MystIII 1.2 patched nocd
hack. For some reason... it copied fine and
installed after that. I know that's not much help.
Look for a nocd Tribes 2 patch and burn
cd and replace the games .exe afterwards.
Thats all I can suggest, that and getting some cheap cdr media
