I'm trying to find a patch (xdelta or other) that adds the exclusive Pokemon from HG into SS and vice-versa. IE, catching Growlith (HG exclusive) and Vulpix (SS exclusive) on Route 36 in both games. Would be great if you could catch PokeWalker exclusives as well. I have found a post (HG/SS Mods) with a "No Exclusive Mod", but it is incomplete. For example, Spinarak can be found on Route 30 at night, but not Route 31 or Route 2. If one doesn't exist (I cant seem to find one), how hard would it be to make my own? I know its an odd request, but I'm trying to make" a "complete" version of HG/SS that has all pokemon (including PokeWalker exclusives; minus Wondercard event Pokemon) and removes evolutions restrictions (Kadabra evolving into Alakazam via level up rather then through trading).
