Getting Error 0xC8804478 Failed to read save file backup in Checkpoint - Using Pokemon Black 3DS

[flameboyrgb]

Before anything, let me congratulate you guys for the detailed tutorials and very clear explanations. I was able to homebrew my 3DS and almos edit my save in one go.

However I found the next problem:

I just installed homebrew following the site's instructions step by step in my 3DS.

I am playing my pokemon black cartridge. I loaded checkpoint and managed to create a backup file.

I loaded this file in my pc and opened it in PKHex.

I started messing with pokemon and added a bunch of event pokemon to my boxes. Notice that I'm using a cell phone to edit the contents of my SD card since I have no adapter.

I saved the file in the main folder where the backup was created inside the checkpoint folder.

Took the SD out and inserted in the 3DS again. Loaded Checkpoint. I try to restore the file I just created and get the following error:

Error 0xC8804478 Failed to read save file backup.

When I run the game the save file is unchanged and uncorrupted.

 

I have tried renaming the save file to "main", creating new folders in the Checkpoint directory, erasing the working backup file and replacing it with the PKHex file. But nothing seems to be working. Maybe I overlooked something simple that is preventing me from loading my save in checkpoint?

 

Hope you guys can help.

It happened the same to me before, try to re-do it and analyze yourself. In mycase, the mistake was that I was editing a Mario Kart 7 instead of Pokemon Sun, and after that, it worked.

Did you managed to do?

Try TWLsaveTool. If it still fails there then your cart may be fake.

hi，i just meet the same question.i found it that the file you export may be named 20251105-211147 but the sav file was named POKEMON B.sav originally. So whatever the file is named after you edit your Pokemon，it may be named 20251106-211148(whatever)but the sav file must be POKEMON B.sav(the same as the original).

so as i did this，it worked.

wish it can help you.
