I do not know how to do that.
Just use Pokésav, because it works fine for me. It did not fuck up my save, nor fuck up the game. In fact, I made loads of Backups of my Pokémon SAV Files, so you should've made backups in the first place.
I just finished editing my SAV file and got the Shiny Raikou, Suicune, and Entei! They're shiny and stuff, so everything seems fine.
