Help regarding corrupt OG Crystal Save file from my brother

[hNoori]

I wanted to go into my Brothers Save file to look some stuff up but the game showed me a prompt that the save file was corrupted.

I dont have much hope in fixing it. I just want to know the Playtime of the save and/ or the amount of different pokemon catched.
I remember the Name of the character being "Oni" and him using the female character.
The File can be opened through pkhex but I cant look the trainer info up.
Is there a way to fix that as I only really care about the playtime (and if possible pokedex catch counter)
Thanks to any1 whos willing to help me

PKHeX tells you the playtime at the top of the program window.

The pokedex editor opens just fine.
