The 16GB one goes on the left slot and thats the Linux operating system. Simple and easy to use UI that shows all the games you have. The 64GB card it comes with is the one with the games on it. That goes in the right slot. If you boot the system WITHOUT the 16GB card in, it boots to android instead if youd rather use that, and again, it reads all the games on the 64GB card in the right slot.
