Afterbirth Save Editor
Edits Afterbirth save files.
Created 3 years ago
This is a pretty functional save editor for The Binding of Isaac: Afterbirth. It currently supports editing known stored values like mom kills/eden tokens/etc, endings seen, post-it note progress, collected items, secrets unlocked, bosses defeated, challenges completed, and special seeds unlocked.

It's windows-only, but it should support both steam cloud and offline saves.


Please back up your save files before you edit them to avoid the risk of (permanent) save corruption.


Notes/Instructions:

All three save slots need to exist for this to work. If you don't have save files for slots 2/3, start and stop a new run in those slots before using this.

I would not recommend editing files while the game is open. Close the game before opening the editor and making changes.

For the vast majority of use cases, just hit auto-load and the save editor will automatically locate your steam cloud saves. If you want it to automatically locate your offline saves, uncheck the "using steam cloud saves" box before hitting auto-load -- it'll locate the savedatapath.txt file in your afterbirth exe folder and read a save location from it.

You can manually load a folder using the open manually button -- if the steam cloud folder is checked, load the "250900" folder in your steam userdata folder. If it isn't, load the "The Binding of Isaac Afterbirth" folder in Documents/My Games.

If you're editing steam cloud saves, it will (try to) automatically update the steam cloud hash on save, preventing steam cloud from downloading the stored online save and wiping your edits.
