My game crashed and deleted all my progress? How do I restore my save data?

My game crashed while I was playing, but when I reopened it, all my save data was gone?? I checked the save data folder in dev_hdd0 > home > 00000001 and there's definitely some items in there (Though I'm not sure if this is my actual save data or new save data).
Either way, is there anyway to get back my save data/get the emulator to recognize my save data if I still have it? I've sunk 22 hours into this game and I really don't want to restart.
