PSP Saves Corrupted / Incompatible with real PSP?

So I tried copying all my PSP saves from retroarch/saves/PSP/SAVEDATA to my PS Vita’s ux0:pspemu/PSP/SAVEDATA to use in Adrenaline (equivalent to copying to a real PSP?). Games work but all saves are corrupted and have a broken icon. Is there a fix? Because I wanted to get my achievements in Final Fantasy Dissidia for playing for 30 days without abusing save states for 720 hours total (Every day is Ground Hog’s Day in RetroArch for Playstation Classic: Sep 1st 2018. Why no date change feature for PSP?).
