Any way to fix a corrupted ORAS save?

[oldester]

So my Omega Ruby save file got corrupted a day after I managed to get a shiny Treecko and I'm starting to lose hope on getting the save back, I tried to repair the file via pokemon bank and PKHex but sadly they consider the game corrupted as well so I was wondering if anyone else could take a crack at fixing it since I spent a total of 20 hours SRing for him and I seriously don't want to lose all that effort so any help would be greatly appreciated!
