Successfully downgraded my MH4U N3DS XL, but I think I screwed myself. I used the same memory card to backup multiple 3DS before finally slotting it into the MH4U and running the downgrade, unlinking nands, and going on with my business. I don't have my copy of MH4U anymore, and even though I backed all the stuff up; I can't get it back. Even when I get a .cia of it installed and copy over the save data, I can't get my save back (the game will just say it's unusable and needs to format). It's aggravating because I have the files, but I can't seem to get them to work right. Any chance of rescuing my save data?
