a few years ago i submitted a patch for the Satiator1 firmware to allow it to load CUE+ISO+WAV games. many Saturn games are backed up as BIN+CUE, but i usually convert mine to CUE+ISO+WAV because i like being able to double-click on the audio tracks to hear them and open the data tracks in an archive editor to get at the files without having to mount the whole thing on some manner of virtual drive.
