I have zero experience editing a Pokémon game and my only experience with making my own romhack in general was dabbling a bit with Jhack in EarthBound. I only want to change the regional dex in BW2 so that it's the same as BW's regional dex. Besides the editors for wild encounters and trainer data to replace the non-Unovan Pokémon, what else would I need for this? I want to keep it as vanilla as possible other than the change to available Pokémon in the wild and what the trainers use.
