 It's easy to do; just make sure that the various tables have their entries in the right order: Bulbasaur, Ivysaur, Venusaur, …, Celebi, #252, #253, Egg.
 
 Unfortunately, you can't have more than 253 Pokémon. IDs are one byte each, so they have 256 possible values. Of those values, $00 indicates a lack of a Pokémon; $FF (−1) is an end-of-list marker; and $FD is `EGG` (though you can change this to $FE, as discussed above). If you value having a 254th Pokémon more than allowing breeding, you could replace `EGG`, but you would also have to carefully remove a lot of code that treats `EGG` specially.
