I don't really know much about Pokesav. I have it to look at files for info, but Expert Evan told me that Pokesav can give a saved Pokemon bad trash bytes. So I have avoided using it for anything but viewing sav file info. Also, I'm not sure how to use Pokesav to trade from the a completely computer generated save file as compared to a flash cart file, which runs off of an actual Pokemon Rom. After what EE told me, I decided to never use Pokesav except to look at files. But for this Crobat, I used another editor on an older sav file, just so I could do the crobat, but I'm trashing the file when I'm done, after I trade the crobat to another game.
