Pretty much what the title says. Kinda annoying having to sign up then having to register if I forget.
I use RxTools so cfw is a yeah.Save editors, and ntrcfw cheat plugins exist for most relevant games, and are much safer than powersaves
edit: for other games, there is usually documentation on where specific things are stored in the save file itself, so you can usually just hex edit your save (everything listed here requires homebrew/cfw to use)
