Ys IV: Mask of the Sun - A New Theory (2005)

Ys IV: Mask of the Sun - A New Theory is a remake of the original Ys IV for the Super Famicom. It follows the story of the original, but revamps the combat to be based on a more traditional button-press system than the original game's "bump" combat, based on running into enemies off-center.
