Help with a save file

[Deivid_Gamer]

Hey guys!
Recently a friend sent me a Pokemon Emerald save to see if I could fix it, but I can't.
I can't load it in PKHeX, some roms don't play it and in the rom that I managed to load the save it says it is corrupt.
The file is 64kb, and even converting it to 128kb it is not loaded.

I'll leave a download link for the file here, in case anyone can help me.

Note: In the rom that loaded my save, even though it said it was corrupt, I was able to navigate the game smoothly and capture new Pokemon, but I wanted some way to fix this.
