    I've used the EZ program to transfer the rom to my SD, but in the menu it doesn't show the file size like the other roms, http://imgur.com/JXXTBA2

    and when I try to load it an error comes up saying "Unknown Operation"

    I've tried more than one version of the rom, but no luck. Any ideas? It's the only game that doesn't load on my card.

    it is working perfectly here.. did you try another region? try the rom on an emulator first, maybe its not copied right... after copy the file did you used safe removal on windows?
