Its because the software is the same. So you can still make the internal memory cards, but you just cant play the game. It is just like I think the SD Mem Card slots are under that flap, but the flap is just glued shut, but I dont want to break my PS3 to see if they are under there, then they arent, and I broke my shit lol. But yeah its cuz the software is the same. They cant have everyone with different things, because then updating it is whack and it screws everything up. So yeah...thats why
