I'm convinced that some of the best music ever has come from my Super Nintendo.

(not snes, but mother 3 fixes a lot of the gameplay/tonal consistency issues)

Romhacking.net has a lot of Secret of Mana tweaks like equipment progression balance. If I ever attempt a play-through again I will probably use a few that are compatible. I have often started (on an emulator) and given up because I died a lot and I don't have time for that.
