Pokemon White Corrupted Save File

[Vinnig]

I found my Pokemon White cartridge from several years ago. When I put it into my 3ds, it loads but then goes to a screen saying that the save data cannot be accessed. It prompts me to turn the power off and reinsert the cartridge, but that does not work. I checked PKSM, but the save file didn't even appear. I then created a backup via checkpoint and tried loading the save file into PKHeX. The error message, "Attempted to load an unsupported file type/size." I checked to see if I was using the right settings for Pokemon White, and I was. This led me to believe my cartridge is corrupt. I have attached the save file below. If anyone could help me revive this save file, that would be amazing.

That's not a save file. Try backing up again or try to use JKSV instead.

It doesn't appear in JKSV, is it corrupted that bad?

To my knowledge JKSV doesn't see NDS carts, you may want to try one of the other options:

It's also possible that the savefile is beyond recovery.

I'm fine if I lose the save file, is there any way I can wipe the save? I tried putting a clean save file over my bad one, but it still gave me the error.

Are you sure it's a legitimate cartridge? Restoring a clean savefile should have cleared the error, but bootleg carts would have issues both with reading and writing the savefile.

It's also possible the cart is legitimate, but damaged, in which case I'm unsure what can be done.
