Let me get this straight, is it a Professor SF or a Game Doctor SF 6 that you have?

I tried this myself and was amazed what kind of hoops I had to go through so I'll try to help you a little.

First, The Dumper's rule: If you dumped it yourself, it should work (so try to always dump it yourself if you can).

The Game Doctor SF3?-7 will use a header and for some copy protected games you're going to need to use it so I'd get in the habbit of learning how. First dump a game of the exact same configuration (HiRom, 64K sram, etc.) and save the GD header (512 bytes). Next get a ROM in *.smc format and (THIS IS CRITICAL) you MUST verify the header matches your game parameters by either manually looking at the header with a hex editor or using some program that verifies it against the game (I don't know of one that does this) or writing your own utility to do this. If your smc header is off (and in my experience many that you find on the net are) you'll be screwed so don't let that happen -- check it! Next, use a utility (Snes tool, insnest) to convert the ROM to Game Doctor format, this will probably save it without the header. Next add the header saved above (or replace the header you got from letting the utility program convert it with the known good header you saved). Now you should be golden, everything should work! If it doesn't, take two asprin and don't call me :)

Why, you might ask do we go to all the trouble of dumping our own header and grafting it on to the ROM image when there are utilities out there that should do that? Because most utilities don't put the GD header on and the one I found that did had a bug in the GD header generation code.

Because it is pretty tricky to get right the first time I'll give you an example of what the output should look like for Secret of Mana: SoM.zip

Enjoy
