Comment 1: Carl Industries (US importers) and Bung Enterprises presents the Professor SF. The Professor SF is the American version of Hong Kong's Game Doctor SF 6. It's almost as good as it's sequel, the Professor SF II. The only real noticeable differences are the GUI, and the de-protect functions. This is a decent copier, however, it's a real pain to convert roms to the special format. One advantage is that the hardware is sturdy, this sucker is built like a tank. The copier comes with a built in 3.5" disk drive and 32Mbit memory. The great feature of the Professor line is that you can keep games loaded into memory even when the copier is off! This is very helpful, along with the real-time save, slow motion function, and cheat code input. With the special blue passthrough connector you can even have DSP support. The GUI is decent, just a standard menu system with self-test, copy, rename, disk format (1600K, 1440K, and 720K), delete, BRAM transfer, etc. There is also an option to switch to Japanese, Chinese, or English. No music, sound effects, or anything fancy like the SWCDX series though. The only real drawback is that the de-protect function isn't as good as some other copiers. I only really noticed this when I tried to play Donkey Kong Country, and you can overcome this with patches. The power supply used can be anywhere from DC 9V-12Volts and 850mA-1.5Amps, making it very versitile. The parallel port can be connected to a computer or the optional CD drive, which makes it possible to use ROM CDs.

There seem to be be two versions. This one works with Doctor PC Junior, SF6(Prof. 1) and SF7 (Prof. 2). CDs were made with hundreds of SNES/SFC games on, see the Pirate section to see an example. It looks like the user had to place the CD in that plasic holder then put it in the drive.
This newer CD reader unit, the SFCD7, is for use with the Game Doctor
SF7 (Professor SF2). Its designed for use with SNES CDs for fast loading
of your favourite games, and also has the function of playing music CD's
through the headphone jack. Its all controllable through the GUI of the
backup unit too.
A MPEG card is (was) being developed that allows you to play MPEG video
CDs, that is installed into the SF7 itself. You can also play music CDs
in the drive, and control the CD via a GUI interface (like playing music
on the Sega CD)
