They can't dump original games AFAIK, but you can use them to run backup ROMs or homebrew ROMs. When I can get some money put back, I plan on using one of the Genesis 64Mbit carts as a homebrew development system.
They backup original games just fine. I haven't tried a LOT of games, but all the ones I've tried dumped just fine.

EDIT: I'm working on 48 hours with not much sleep, please forgive me. I'm thinking of my MGH (MultiGame Hunter) that I've dumped Genesis games with. I don't really remember if I've dumped games with Tototek's card or not. I will pull it out and try it tonight.
