Pokemon Fire red - corrupted save file

[Balzat]

I was playing pokemon fire red on advance SP with Super card SD and the battery ran out while saving. After turning my console back on, I get the message "The save file has been deleted ..."
Is there any chance to fix my save file?

It might be possible to fix this. However save block 1 is gone. That's where your party and items are stored.

I haven't tried but I think I could restore your save with a copy of the block from another save. Do you have any older backup of your save?

Also to prevent future issues you should check your Supercard settings and see if you can get the save size set to 128KB.

Edit:
This is the best I could restore from your save by using block 1 from a new save: firered.sav
