Leaf Green corrupted save

Hey all

My save is suddenly got corrupted. Maybe closed the emu before save complete. I don't remember exactly what i did because i didn't open pc for 2-3 days afterwards.

results of opening in different programs:

VisualBoyAdvance(link): doesn't recognize at all, just acting as there is nothing there starts a fresh game. (Before you say VBALink uses different saves, I am opening game in 2nd vba and save extension is ".sa2")

Platinum Migrate from leaf green (Desmume): Tells me there is no save or it's corrupted. I know it is recognizing the save because if it don't there will be no Migrate option from the start.

PokeHEX: binary is not compatible with save file or something like that.

Is it completely lost? There are some Hard work in there i don't wanna start over.
