To make a short story shorter, I updated my firmware to 1.19 so it would work with the 3DS. At first I played it on my DSi XL like normal, but then decided to see if it would work on my 3DS. It did, but now it won't work on my DSi XL. I tried to quick format it, but that didn't work. I'm not sure why it would have either. So basically, the card will work on my 3DS XL, but not my DSi XL anymore. It says there's no cartridge in the device when I do. And this literally happened after I put it in my 3DS XL. As before hand I was using it in my DSi XL just fine. Now all of a sudden it refuses to show and still shows on the 3DS XL. I would rather play it on my DSi XL too... Any ideas?
