I have changed it so that the Pokemon you encounter and battle are all Pokemon from the first 2 Gens of Pokemon, Kanto and Johto or RBY and GSC. I was inspired by this and decided to make a sort of spiritual successor. Recently I played a hack called Pokemon White 151 which replaces all the Gen 5 Pokemon with Gen 1 Pokemon. Gen 5 is my favourite Gen and I have played them a lot of times. Hi there, this is my first hack and its relatively simple.
