This site has a very very great database of EVERY SINGLE SNES & SFC game ever released! http://mercenaryforce.web.fc2.com/superfamicom/snes/RPG.html
EDIT: could "Obitus" be the game your looking for? http://www.youtube.com/watch?v=s4Z3ShxvJpY
Looking at it, Obitus has roughly the same method of scrolling as the game that I remember. It also has a similar vibe.
Those are the only similarities, though.
UPDATE: The game itself played similarly to Might & Magic III's snes port, but not exactly so.
Thinking about it now, the game was almost like a Might & Magic clone of sorts that played slightly differently.
To describe it best, the game that I remember was like a mixture between Might & Magic III and Eye of the Beholder, with a character selection screen very similar to that of Heroes of Might & Magic.
Basically, if one took Might & Magic III's engine, applied some of the things that Eye of the Beholder had in common with what my description said, then put in a bigger version of the character select screen from Heroes of Might & Magic, it would be golden!
Superficially, the game is Eye of the Beholder, but visually, it looks more like Might & Magic III, save the death faces and game over screen (although the game over screen does not have the skulls on it, so it is not perfect either for the description).
Some things just aren't adding up.
I can only return to my hypothesis of this being some strange obscure homebrew.
As a mock-up of sorts, this is a LOT like the game that I remember.
Not as much as the previous, but this also looks similar:http://www.youtube.com/watch?v=oa9wz2p3ghQ
