Periodically while playing, I will get a notification that says "save file corrupted. Reverting to previous save". After this happened a few times, I just started using save states in my emulator after I save the game in the menu. I have yet to experience this bug on my Gameboy Advance with a flash cart, but the emulator I am using is the Retroarch Gameboy Advance core mGBA 0.10-dev 5d48e07.
I wish I had something more definitive to provide. It's not an every time thing, but it's probably 1/10 saves made where this happens.
