Seems like the save glitched out. Maybe try using the reader to completely delete your save. I’ve had similar stuff happen to my Crystal save before (mons appeared in my PC, and the corruption spread, overwriting other PC slots), and even wiping the save in-game carried the glitchiness over to a new save. Tho, if wiping the save using the reader didn’t fix it, then it’s possibly a cart issue. [to elaborate, I originally gave up a PC box to corruption, and it stayed for a while. Like I was able to play normally after forsaking that one box. But eventually I noticed some mons going missing, as tho the corruption spread]

Just wait for a stable update, for crying out loud. and you won’t “lose it for good”. Just keep it in the save. Or back it up into a file. Just wait patiently, alright. :3

The save is ok, but your emulator filled the the rest of the file with empty data. Try using a newer version of DesMuMe http://desmume.org/download/ 4 - Pokemon Black 2.dsv

Just says the files corrupted, Thank you for tryin to help. I’m going to try a couple things and see what works, and if any do I’ll respond back here with it. Again thank you !

Read that part again. Apparently, the new Arceus update increased the SAV file size. Gotta wait for PKHeX to be updated to support that.
