this is an instructable on how to use Pokesav which can be found here
. just click on the download pokesav link and a message will prompt to open it. just download it and open it up, and you should get a window that has a whole bunch of stuff that looks like this.EDIT: For those of you who want to make legit, super powerful mega charged pokemon, go here. It's a pokedex with all the pokemon and stats and everything you need to know. In other words, check out the pokemon you want to create, make only a couple of the stats maxed out for that pokemon. For example:
Raichu = make Special Attack and Special Defence stats really good because that's closer to normality
Garchomp = make Attack stat really supercharged because it can.
DO NOT SUPERCHARGE LEGENDARIES because now, that's just cheap, rigged,and downright virtually imposible.
Oh, and for that link, there's also a whole bunch of goodies that will help you on your pokemon journey and hacking :). Okay, maybe just journey, but things like damage calculator, balanced team tester, etc will help you lots.
