@Black_Knight_00: platformer, kind of like NES Rygar

Hi, I'm looking for an old, probably late 90s NES game.

There were like 3 playable characters and one of them had a gun and an ability to teleport back to a place where he left some kind of a rock with a diamond inside(?). At least one of the other characters had more old-fashioned weapon like a sword or an axe. It was probably an adventure/rpg game.
