I have a 128gb micro sd card that works with my phone and my 3ds. Is it possible to use this SD card to store games instead of using the ones that Sony sell?
Sony decided to be assholes with the Vita and restrict the storage to use specific memory sticks that only Sony make. These overpriced cards are the only ones that you can use with the Vita. There is no option to use any standard SD cards with the PlayStation Vita.
