So I was playing Pokemon Black 2 , and I had my save states of my game. Then, I heard of autosaving and its importance, so during my game I went into the emulator settings and checked autosaving, along with some other info. When I exited the emulator settings and went back to my game, the lag increased immediately in game, the music was on loop, and the game froze if I interacted with people and turned black when I exited the town. I think it's cause I changed the emulator's settings during the game, and now my savestate is possibly corrupted. I can load the save just fine and move around, but if i leave the city or check my ingame (not emulator) settings, the game freezes.
After undoing my emulator setting changes, I started another game and that works just fine with saving/loading. Is there anyway to salvage the last save? I invested alot of time in it and I'd really hate to lose it
