Hie, I'm Dawyde, I'm French (sorry for my bad English), I want to make a save editor for Animal Crossing : Let's go to the city as ACToolkit.
I started programing (PHP/Javascript), now, my editor can "read" pockets and drawers of the 1st resident, but if I change an object, the save is corupted.
I opened the corupt save with ACToolkit and I had this message : "Checksums are invalid! Continue aniway ?". If I save with ACToolkit, my save work...
How to generate Checksums ?
