I don't know about the tuna's, but I know you can make a fmcb card from another. iirc, it doesn't involve making an image, but just using the first card to get your foot in the door, so to speak, then making another fmcb card from that. I made a second after buying a fmcb, when I owned a ps2, but I gave one or both cards to the person I sold it to. if I ever buy another ps2, it will have to have a working dvd player, which this one did, as I'd go legit on it. I kinda wish I hadn't sold the system for that very fact. I also sold it with a brook adapter to enable dualsense on the ps2 wirelessly. stupid mistake, I guess.
