I have an 8GB and ps vita slim and it's hacked and I've been putting games and deleting I've been trying to see which games I want to play but every time now I delete a game the memory doesn't go down it doesn't free it up. For example I deleted all the games installed now i still got 1 gig left ? Which makes no sense. Also i don't transfer my games through ftp I do it through vitashell via USB
