Right now I'm trying to figure out if there's a way to add a "dash button" to Final Fantasy IV (J). Do I need to learn Assembly, or am I barking up the wrong tree?
EDIT: I've found my first lead, in the form of a PAR code:
This enables fast walking, not only in towns and dungeons, but also quite comically during story scenes. Nothing spectacular, but a good start. I should note that this is much faster than I would have liked, and of course, I want to include the functionality of having to press the cancel button in order to activate the ability.
EDIT 2: I figured something out:
If I edit the code in blue to 7E06AC01, I get a Cecil that walks at the speed I want, but again, this is everywhere, in towns, dungeons, on the world map, during story scenes, everywhere.
