Ok, here's a list of SNES RPGs. I have already taken the liberty of eliminating ones that shouldn't be considered candidates (Final Fantasy, Zelda).
7th Saga
Arcana
Breath of Fire 1
Breath of Fire 2
Dungeon Master
Earthbound (Mother 2)
Estopolis 1 (Lufia & the Fortress of Doom)
Estopolis 2 (Lufia 2: Rise of the Sinistrals)
Eye of the Beholder
Lagoon
Lufia & the Fortress of Doom (Estopolis 1)
Lufia 2: Rise of the Sinistrals (Estopolis 2)
Might & Magic 3: Isles of Terra
Paladin's Quest
Robotrek
Romancing Saga 3
Secret of the Stars
Soul Blazer
Soul Blazer 2 (Illusion of Gaia) (Illusion of Time)
Soul Blazer 3 (Terranigma)
Terranigma (Soul Blazer 3)
Ultima 6: The False Prophet
Ultima 7: The Black Gate
Ultima: Runes of Virtue 2
Uncharted Waters
Uncharted Waters 2: New Horizons
Wizardry 5: Heart of the Maelstrom
I'm guessing it's not an Ultima or Wizardry. Uncharted can probably be eliminated, as well as (most likely) the Soul Blazer/Terranigma series. Doubt it's Lagoon or the Lufia/Estopolis series. Can probably knock out Robotrek (it being in space with robots). Might and Magic is out. Probably not Eye of the Beholder, Earthbound, or Breath of Fire. I'd throw out 7th Saga and Arcana also.
That just leaves:
Secret of the Stars
Romancing Saga 3
Paladin's Quest
Dungeon Master
Could it be Secret of the Stars? Video below:

Or Paladin's Quest?
