ROM Hack Corrupted save Ultra Moon

[DivCanuck]

Hello everyone,

I recently homebrewed my 3DS and used PkHeX and JKSM to generate some pokemon in Ultra Moon, but whenever I try to open the game it says something along the lines of "the saved game data has been corrupted, read owners manual ..." I have already tried deleting the secure value, but nothing happened. Does anyone have any tips? All help is appreciated.

Edit: Issue resovled. Scroll all the way down for a fix

You kept a backup, right? You didn't overwrite the initial backup, and instead put the modified save somewhere else, right? Did you let PKHeX save backups for you?

What do you mean by that?

What do you mean by that?

A copy of the save before you made your edits. Before you could use it with PKHeX, you had to dump it first. Did you overwrite or delete that dump?

 

[DivCanuck]

I think so

I think so

Restore that save then, and see if it still works.

Do you know if it will make a difference if I save to main and not backup?

"Save backup" seems to just have a different filename, the contents is the same. PKHeX can also automatically backup saves any time you save if you enable this feature (create a "bak" folder next to the PKHeX executable).

Could you take a screenshot of what you mean? I'm still a bit confused about this

I don't know what to "screenshot" for this. Do you have the "main" file from before you made your edits in PKHeX?

 

[DivCanuck]

Yes

 

[ihaveahax]

Yes

Restore that using JKSM then. Remember where you found it on the SD card? Put the original "main" file back there, and use JKSM to restore it.

I'm sorry if I sound very naive but how do I "restore" a file?

Go to the same place you did to backup the save, but choose to restore it instead.

Thank you very much, I will try this a bit later. One more question, do you know of any ways that I can avoid corrupted save files?

Keep backups before you make edits. That's the best advice, really.

Turns out I didn't keep a copy of my saves. I guess I should just restart the game. Good thing I didn't any important Pokemon into the game

Edit: My game is good now, all I did was get a copy of my main file (which I ended up having) dragging it into PkHeX and saving it to my main file. All my generated Pokemon are gone, but I can always just recreate them. Thank you for all of your help.
