Recovering Pokemon Yellow Save

[orivero1997]

So I got the save is destroyed message on my copy of Yellow I was about to complete the Pokedex on. Someone on Reddit told me I could use Pkhex to try and save it but I really don't know how. I already backed up the sav but I cant open it in Pkhex, from what I've read I have to use a hex editor or something for it to open.

I really don't know much about this stuff and I just want to try and recover all my work. I'll attach my save in case anyone wants to try and look at it. I appreciate any and all help and sorry if this is annoying or a dumb post I'm completely new to this and this seemed like the most helpful forum.

Attached file is just junk.

Open it in a hex editor, and compare the overall visuals to a valid Yellow save file.

@Kaphotics Could you link me a hex editor you recommend? And maybe I backed up the save wrong, I'm using the GB Operator software and I just clicked back up save. Sorry if I sound dumb btw.

HxD works fine.

Bad dumps can be from dirty contacts on the cartridge, or a bad/fake cartridge.

If there's only junk, then there's nothing to recover

Can you see if this dump is any better? I put it into HxD but I cant tell what I'm supposed to be looking for.

Same junk. If whatever is being dumped is what is on the cart, then there isn't any valid save data to recover / use.
