Those pesky black-bottom GameShark 2, Xploder, and the (silver bottom) Code Breakers are among the newly supported/dumpable discs in the latest redumper build https://github.com/superg/redumper/releases
with command --rings --correct-offset-shift
Unlicensed lists here are a work in progress:

Europe - http://wiki.redump.org/index.php?title= … ensed_List
Asia - http://wiki.redump.org/index.php?title= … ensed_List
So far the only kind of PS2 cheat discs that CAN'T be dumped are the ones with physical separator rings (Swap Magic, HD Advance etc).
Notes:
Try using Asus and different models of Plextors if you're hitting c2 errors. Some drives have errors reading while others read fine.
