Okay, so I'll start from the beginning. I bought an SD card from a seller on etsy , and it works perfectly with my raspberry pi 3 model B. It boots, and EmulationStation comes up. (Sorry if i'm not using correct computer terms, I am very new to raspberry pi, so excuse my lack of knowledge.)
Keep in mind that I do NOT have a keyboard to type ANYTHING into the terminal. I have a Logitech controller, but I'm not sure that i can get it hooked up with retropie without a keyboard. Any help would be greatly appreciated!
