I have this same problem. I downloaded a lot of games on 3dox iso emulator. I threw them into the folder roms and wanted to move to disk via ftp HDD1, unfortunately, a message pops up when copying iso (invalid file handle). Iso files copied to an external drive and I wanted to copy them in FSD unfortunately when you try to copy, nothing moves, I used the XEXmenu and also nothing happens. Do you know how to help me? I'm sorry my English is poor.Ps. I downloaded pack of games Thepirate... A Huge Collection Of 3DO Games + Emulator & Bios partI/partII/partIII .
Now I downloaded another game (from another source) and is easily copied. The problem probably lies in these games.
