to be honest, when it came to the decision what to use nex, i had the same fear of new thingy like you have, but I figured out very fast that pokegen is the best choice to be made when it comes to get legal Pokemons for your games, as Pokesav suffers from a bad PID support for legal PID´s and i only use PSav for creating the Bag-Codes noting more nothing less, Pokemons will be only made in Pokegen (as it has a very good working PID generator for legal Pokemons......i only wanted to get more PID´s specialy for Shiny PKMN with specific Nature and Hidden POwer at PowerLvL. 70!)
