Pokémon Black Version 2: Pokemon Black 2 Unova Dex

Here's a simple patch for Pokemon Black 2 that lets you fill your Unova Dex without the need for trade!

White 2 version exclusives and event legendaries can be found in the wild, and Pokemon that evolved by trading have been altered. Everything else should be the same as the vanilla game.


Special thanks to the Pokemon romhacking community and Drayano, KazoWAR, and Andibad for their extremely helpful tools, without which this wouldn't have been possible. Also thank you to Moltz, whose hack provided the inspiration to make this.

Instructions:
Apply the xdelta file to an unheadered, clean Black 2 ROM using the patcher of your choice.
