I've been looking, however everything I find seems to only be for FR. A couple examples that I have run across that claim to work for Ruby are only the same as for FR, and in fact have not worked, at least when I have tried to implement them.
I am intending to enable the National Dex in my hack so all pokemon are recorded as you progress, instead of having a lack of pokemon entries in the pokedex when you're halfway through the game with a large number of different pokemon. I am also introducing some Pokemon that are Series Exclusive, such as Crystal Onix, Venustoise, and Psyduck(with Shellder attached), and a few others.
Another bit I'm looking for, is to repoint the Dex entries for the ???????? pokemon so that they all read the Dex data for the 0 slot before Bulbasaur.
