I recently misplaced my game card for Pokemon Y. I downloaded the game so I wouldn't lose it again, not realizing until afterwards that downloaded games don't work with save files from game cards, even if they're the exact same game. My questions are:
-Is this true? (I have not done any sort of system transfer)
-Can I put just the game on a different card without transferring anything else (either through system transfer or by deleting and re-downloading on another card)?
-If I delete the game, will that also delete the game card's save file? The game itself may be able to tell the difference, but I'm not sure other software can.
-Just a double-check: the save file will still work if I buy a replacement game card, right?
