You don't need to use it, but it is a lot simpler.
Aarux, I suggest you learn how to fix trash bytes manually
Also, here is the guide to manual, and it also has a link to the Trash Byte Normalizer: http://projectpokemon.org/wiki/Trash_Bytes
Report him yourself, you don't need to have any special privileges to do so.
I have infracted him, hopefully he wont do it again (even though he will )
That doesn't make any sense.
Firstly, if the PP is the same, it just saves time using Pokesav to do it.
Secondly, if you edit pokemon straight into storage, seal co-ordinates don't exist in the file.
Thirdly, please make more sense next time.
You could've just used HxD to add blank bytes into the pkm file, then load it into pokesav and go into stats edit.
But I guess this is easier (albeit not as fun )
