I've noticed also that the game keeps the save file from a later episode and translates it into the earlier episode, and so I was planning on using it to get obtainable Pokemon from earlier versions only (because, and I'm sorry for saying this, but the options you get early game in later versions are just awful compared to earlier versions and I need every bit of strength I can get to defeat this insanely difficult game). I know episode 9 has certain obtainable Pokemon in it for a fact that I want on my main team and I think this method is legitimate for a game that uses competitive teams during Gym fights and already has a limited number of Pokemon obtainable in the game at all. To me, I want to have the chance everyone else had when Reborn had just started, and so that is my aim.
