>>28593852Powersave isn't bad, it just takes more work than pkhex.
The main thing about powersave is you have to modify existing pokemon for them to be legal, whereas pkhex can just generate them.
Also powersaves require a lot of moving the cartridge around, since most of the codes can only modify a single pokemon at a time.
My typical process with powersave was to acquire the pokemon I wanted to make, breed it, then modify the ivs and nature etc etc of the offspring. I don't know if that is the most efficient way but it is the only one I could come up with to make a seemingly legitimate mon.
