Hello, I'm new to the SKY3DS (just got mine today). I'm using a SanDisk ultra 16gb microsd (bought from mymemory) along side the SKY3DS, for some reason it doesn't change games when pushing the button. To change games I have to press the button and eject the card and reinsert it for a new game. If I press the button and it flashes it just stays flashing and doesn't switch games, if I press the button after ejecting and reinsert in, it sometimes stays solid only then after ejecting again will it change games. Is this a fault with the microsd as I don't have a spare at the moment. I am thinking of getting one of these LEXAR 32GB HIGH SPEED MICRO SDHC CARD 633X CLASS 10 UHS-I U1 90MB/S + USB 3.0 READER, there currently £17 so if anyone has used one in a SKY3DS please let me know.
