I've been searching all over for romhacks of Pokemon Blue and Pokemon Crystal that only alter the game to the point where you have running shoes. I know Pokemon Warp Blue adds this, but I don't want to have the fast travel points and other changes. Similarly Perfect Crystal adds running shoes to the game, and also makes all pokemon available (I actually really like this, only modification aside from the running shoes I'd be happy with) but it has some other changes that I don't really want.
I was wondering if anyone knew if there was a hack of either of these games that only added running shoes. If not, is it possible to modify the IPS file of these hacks to remove all changes but the running shoes (even more ideally, with perfect crystal not removing the all pokemon being available mod, but that I'm going to guess is a lot more complicated).
I have IPS Peek installed, as well as a hex editor but I don't have any idea what to start fiddling around with. Either pointing me to a vanilla romhack with just shoes, or some advice (if its possible) on a way to selectively remove changes using one of the two aforementioned hacks.
