For anyone curious, here's the Circle of the Moon ROM with a patch that lets you move like in Symphony of the Night/Harmony of Dissonance/Aria of Sorrow where running is always automatic.
Just turn the "N" to "Y" with A at the start on "Always run".

Play this if you hated the double tap run. Or if you're like >>712967520 and need to play what they're suggesting before talking out of their ass.
