Yes, the 4 upper ones become the C buttons(up down left right) just like an n64 controller, and the lower green and red work as A and B. The other emulators just use the upper ones as ABXY.

yeah, I thought about that, the thing is, those are 3.7v batteries, I would have to use a step-up circuit to get it up to 5v (wich I did at first, using an Adafruit Powerboost 1000c and 2 samsung 18650 batteries), but the only ones I found did give like 1amp of power for the total system, and the new Raspberry Pi 3 needs more than that to work. So there's probably another, better way to make it work with a slimmer battery, but considering my options, and my little experience with electronics, I chose the RC battery option, with an external charger. Im open to suggestions if you know a way to make it work. Thanks!(Here's a picture of the original 18650 compartment, was waay slimmer)

I'll translate it in a few days!
