An all around tool for Black and White, allowing editing of species, moves, encounter slots and evolutions. Be warned that Pokémon ROM Changer works on absolute offsets, so any sort of extensions whatsoever will stop the program from working if the offsets it's targeting are shifted. May be best used on a fresh ROM to edit what you want, then transplanting the NARCs to your overall project. Unsure who the original developer was but Andibad provided the translation for English users.
