Forgive my misunderstanding, but is this not possible by just changing the "Show Map Name" setting? I previously wanted to do this for my hack, which is based on Emerald. All I had to do is change the petting from "Do not show name" to "05 ???" and That enabled the running shoes while indoors, in any building. And in FireRed it's "02 ???". Although from the amount of 0x2's I see in the first post, that's probably what you were saying. Though... Are you saying that once this code is implemented, you'll be able to run everywhere, regardless of the Show Name setting? Because if that's what you were saying... That is cool. Sorry, for not understanding properly.
