Okay, so I'm one of those people that originally got this for the reviews, and I only used it once. I'd like to know if I could use other cart's game saves. I tried this with SM3DL, but my save was corrupted, and I had to start over. I haven't used the SaveDongle since then, but I'd like to try it to use other Cart's saves. Like, a 100% Mario Kart 7 Save, or a 100% SM3DL save.
