Accidentally deleted Pokémon Emerald save, didn’t overwrite it. Any recovery options?

[Miguel B]

A long time ago, I tried using a backup tool (on a R4) to back up the save from my original Pokémon Emerald cartridge, but I accidentally chose the wrong option and deleted the save instead.

After that, I never started a new game. I only briefly launched the game once, just to check that the save was really gone. I never even selected the option "new game", much less made a new save.

Is there any way to recover the save, even partially?
If yes, please let me know how to do it. I am willing to follow step-by-step instructions.

Thanks in advance.
 

I'm leaving backups of the post-loss saves attached in case anyone can recover them, please. I would be immensely grateful if anyone can.

@Miguel B I looked at the saves in a hex editor and unfortunately there is absolutely nothing there to recover. The file is filled with repeating FF hex values so there is nothing that can be done.

@Poke JI see. Thank you very much for checking for me, I guess there's nothing to be done then (please correct me if I'm wrong).
