Did you mean the Magic Sword? I don't recall having a hint for the Master Sword...
I also don't think number of hearts matters, when getting swords... unless it's hardcoded into ZC to not give you swords until a certain number of HCs whether it's a normal pickup or a special item...
The magic sword or the 3rd sword. There is a cave that gives hints for swords. One cost 120 the other I think is 2... something. I am using 192b184 to play this and so far no problems.
