Need help restoring my one of my childhood Diamond saves!

[annieonthings]

Hi everyone! For years and years now, I’ve held onto one of my few remaining, non-transferred-everything-out saves. Whenever I load up my Pokemon Diamond save, be it from the cartridge or emulators, my save opens to a blank black screen. Rarely, I’ve been able to get to the journal screen. New games work, but haven’t been able to push the save file past the journal or black screen.

Unfortunately, the save file has been compromised with light Action Replay use. As far as I remember, only for rare candies and BP - I originally made this game after I wanted to finish the Pokédex more “legitimately” after using AR heavily on my Pearl version.
I’ve tried editing my position on the map, removing any supposedly illegal Pokémon, but I think my issue is more out of my realm than my research led me to believe. It would mean the world to me if someone is able to get it back to normal! Thank you so much for your time  I’ve attached the unedited save to the post.
