Exactly. My old Ice White 3DS is defective when ACNL is being played, yet every other game I had on that system is working flawlessly. Occasionally, when it tries to load anything, the game would crash and bring me back to the HOME Menu. I've transferred everything to my 3DS XL, and it's working perfectly since then. Same thing when I made it to the New 3DS model.
I'm not sure on what exactly did you meant when you said that you sounded stupid years ago. You didn't posed any problem to me as far as I know, therefore apology accepted.
