Hacking Question mismatch titlekey & titleid - nsp - corrupt save error

[simbin]

Back when I first started building nsp files from the command prompt..
I accidentally got the wrong titlekey or titleid in one of them.

Now with the fixed nsp, I still just get the corrupt save error.

Is there a way to correct that single entry in the Switch database, without wiping everything?

Sadly when it happened to me I had to restore a nand backup.
If you're going that way, make sure to backup all your save data.
