Description by auction seller: You can use the SUPERCOM PRO.1 convertor & saver device to play IMPORT famicom games and save any game at any time on SNES. And SUPERCOM device has two communication I/O ports for you to connect with COM and DISK driver, so you can easily copy the game card to a disk or change the data in the saver. No external power is required for this device, just plug in the system as an adaptor.
Comment 1: This is a new version of the Super Magicom out in Hong Kong only which is called Super Com Pro #. This Super Com is a little bit smaller than SMC and it does not require specially formatted disks, you can use DOS formatted 720K, 1.44M and 1.6M disks (like the MGH). Don't confuse this unit with the copiers by Hi-Speed. I think this was made back when FFE and CCL were working together on projects.
